The ADAS1134 is a 128-channel, current-to-digital, analog-to-digital
converter (ADC). It contains 128 low power, low noise,
low input current integrators, simultaneous sample-and-holds,
and two high speed, high resolution ADCs with configurable
sampling rate and resolutions up to 24 bits.
All converted channel results are output on a single, low voltage
differential signaling (LVDS), self clocked serial interface,
which reduces external hardware.
An SPI-compatible serial interface allows configuration of the
ADC using the SDI input. The SDO output allows the user to
daisy-chain several ADCs on a single, 3-wire bus. The ADAS1134
uses IOVDD, a separate supply, to reduce digital noise effect on
the conversions.
The ADAS1134 is available in a 10 mm × 10 mm, 242-ball
CSP_BGA package.
