The ADuM7703 is a high performance, second-order, Σ-Δ analog-to-digital converter (ADC) with an integrated low dropout (LDO) regulator that converts an analog input signal into a high speed, single-bit data stream with on-chip digital isolation based on Analog Devices, Inc., iCoupler^® technology. The device operates from a 4.5 V to 20 V power supply range (V_DD1) and accepts a pseudo differential input signal of ±250 mV (±320 mV full-scale). The pseudo differential input is ideally suited to shunt voltage monitoring in high voltage applications where galvanic isolation is required.

The analog input is continuously sampled by a high performance analog modulator and converted to a ones density digital output stream with a data rate of up to 21 MHz. The original information can be reconstructed with an appropriate sinc3 digital filter to achieve an 86 dB signal-to-noise ratio (SNR) at 78.1 kSPS with a 256 decimation rate and a 20 MHz master clock. The serial input and output operates from a 5 V or a 3.3 V supply (V_DD2).

The serial interface is digitally isolated. High speed complementary metal-oxide semiconductor (CMOS) technology, combined with monolithic transformer technology, results in the on-chip isolation providing outstanding performance characteristics, superior to alternatives such as optocoupler devices. The ADuM7703 device is available in a 16-lead, wide-body SOIC with an operating temperature range of −40°C to +125°C and an 8-lead, wide-body SOIC with an operating temperature range of −40°C to +105°C.

Applications

• Shunt current monitoring
• AC motor controls
• Power and solar inverters
• Wind turbine inverters
• Analog-to-digital and optoisolator replacement

The ADuM4122 is an isolated, single device, dual output driver that uses iCoupler^® technology to provide precision isolation. The ADuM4122 provides 5 kV rms isolation in the wide-body, 8-lead SOIC package. These isolation components combine high speed complementary metal-oxide semiconductor (CMOS) and monolithic transformer technology to provide performance characteristics superior to alternatives (such as a combination of pulse transformers and gate drivers).

The ADuM4122 operates with an input supply voltage range from 3.3 V to 6.5 V, providing compatibility with lower voltage systems. Unlike gate drivers that employ high voltage level translation methodologies, the ADuM4122 offers true galvanic isolation between the input and the output regions.

The ADuM4122 includes two output pins that facilitate slew rate control of two output drive strengths. The V_OUT pin follows the logic of the V_IN+ pin, while the boosting output, V_{OUT_SRC}, can be toggled to follow the V_IN+ pin or to go high-Z. The toggling of the slew rate is controlled by the primary side. Slew rate control can allow for electromagnetic interference (EMI) mitigation and voltage overshoot control.

An internal thermal shutdown sets outputs low if internal temperatures on the ADuM4122 exceed the thermal shutdown temperature.

As a result, the ADuM4122 provides reliable control over the switching characteristics of insulated gate bipolar transistor (IGBT) and metal-oxide semiconductor field effect transistor (MOSFET) configurations over a wide range of switching voltages, allowing for simple slew rate control.

The ADIS16467 is a precision, microelectric mechanical system (MEMS), inertial measurement unit (IMU) that includes a triaxial gyroscope and a triaxial accelerometer. Each inertial sensor in the ADIS16467 combines with signal conditioning to optimize dynamic performance. The factory calibration characterizes each sensor for sensitivity, bias, alignment, linear acceleration (gyroscope bias), and point of percussion (accelerometer location). Therefore, each sensor has dynamic compensation formulas that provide accurate sensor measurements over a broad set of conditions.

The ADIS16467 provides a simple, cost effective method for integrating accurate, multiaxis inertial sensing into industrial systems, especially when compared to the complexity and investment associated with discrete designs. All necessary motion testing and calibration are part of the production process at the factory, greatly reducing system integration time. Tight orthogonal alignment simplifies inertial frame alignment in navigation systems. The serial peripheral interface (SPI) and register structure provide a simple interface for data collection and configuration control.

The ADIS16467 is in an aluminum module package that is approximately 22.4 mm × 24.3 mm × 9 mm with a 14-lead connector interface.

The ADIN1300 is a low power, single port, Gigabit Ethernet transceiver with low latency and power consumption specifications primarily designed for industrial Ethernet applications.

This design integrates an energy efficient Ethernet (EEE) physical layer device (PHY) core with all associated common analog circuitry, input and output clock buffering, management interface and subsystem registers, and MAC interface and control logic to manage the reset and clock control and pin configuration.

The ADIN1300 is available in a 6 mm × 6 mm, 40-lead lead frame chip scale package (LFCSP). The device operates with a minimum of 2 power supplies, 0.9 V and 3.3 V, assuming the use of a 3.3 V MAC interface supply. For maximum flexibility in system level design, a separate VDDIO supply enables the management data input/output (MDIO) and MAC interface supply voltages to be configured independently of the other circuitry on the ADIN1300, allowing operation at 1.8 V, 2.5 V, or 3.3 V. At power-up, the ADIN1300 is held in hardware reset until each of the supplies has crossed its minimum rising threshold value. Brown-out protection is provided by monitoring the supplies to detect if one or more supply drops below a minimum falling threshold (see Table 17 on the datasheet), and holding the device in hardware reset until the power supplies return and satisfy the power-on reset (POR) circuit.

The MII management interface (also referred to as MDIO interface) provides a 2-wire serial interface between a host processor or MAC (also known as management station (STA)) and the ADIN1300, allowing access to control and status information in the PHY core management registers. The interface is compatible with both the IEEE 802.3 Standard Clause 22 and Clause 45 management frame structures.

The ADIN1300 can support cable lengths up to 150 meters at Gigabit speeds and 180 meters when operating at 100 Mbps or 10 Mbps.

The ADN4654/ADN4655/ADN4656¹  are signal isolated, low voltage differential signaling (LVDS) buffers that operate at up to 1.1 Gbps with low jitter. The devices integrate Analog Devices, Inc., iCoupler^® technology, enhanced for high speed operation to provide galvanic isolation of the TIA/EIA-644-A compliant LVDS drivers and receivers. This integration allows drop-in isolation of an LVDS signal chain.

The ADN4654/ADN4655/ADN4656 comprise multiple channel configurations, and the LVDS receivers on the ADN4655 and ADN4656 include a fail-safe mechanism to ensure a Logic 1 on the corresponding LVDS driver output when the inputs are floating, shorted, or terminated but not driven.

For high speed operation with low jitter, the LVDS and isolator circuits rely on a 2.5 V supply. An integrated on-chip low dropout (LDO) regulator can provide the required 2.5 V from an external 3.3 V power supply. The devices are fully specified over a wide industrial temperature range and come in a 20-lead, wide body SOIC_W package with 5 kV rms isolation or in a 20-lead SSOP package with 3.75 kV rms isolation.
