The ADAS1128 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-holds and two high speed, high resolution ADCs with configurable sampling rate and resolution up to 24 bits.
All converted channel results are output on a single LVDS self-clocked serial interface reducing external hardware.
An SPI-compatible serial interface allows configuration of the ADC using the SDI input. The SDO output allows one to daisy chain several ADCs on a single, 3-wire bus. It uses the separate supply VIO to reduce digital noise effect on the conversions.
The ADAS1128 is housed in a mini-BGA package, 10mm by 10mm.
