ADAS1134

Data Sheet 128-Channel, 24-Bit Current-to-Digital ADC ADAS1134 FEATURES GENERAL DESCRIPTION 128-channel, low level current-to-digital converter Up to 24-bit resolution Up to 22.6 kSPS (44.2 µs integration time) Simultaneous sampling No dead time, no loss of charge Ultralow noise down to 0.32 fC rms (2000 e−) User adjustable full-scale range INL: ±0.05% of reading of ±1.0 ppm FSRI Low power dissipation: 2.25 mW per channel The ADAS1134 is a 128-channel, current-to-digital, analog-todigital 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. LVDS self clocked serial data interface An SPI-compatible serial interface allows configuration of the Serial p...
