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 selfclocked 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.
