Product Details

The ADAS1131 is a 256-channel, current-to-digital analog-to- digital converter (ADC) module. It contains 256 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 of up to 24 bits. The signal chain and sampling architecture of the ADAS1131 is designed to guarantee that all channels are simultaneously sampled, and that no charge is lost throughout the sampling process.

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_x input. The SDO_x output allows the user to daisy-chain several ADCs on a single, 3-wire bus. The ADAS1131 uses the separate supply, IOVDD, to reduce digital noise effect on the conversions.

The ADAS1131 is in a 15 mm × 15 mm, CSP_BGA package.

APPLICATIONS
