ADAS1135 - Current-to-Digital ADC

Description

The ADAS1135 is a 256-channel, current-to-digital, analog-todigital converter (ADC) module.

It contains 256 low power, low noise, low input current integrators, simultaneous sample-andholds, and two high speed, high resolution ADCs with configurable sampling rate and resolutions of up to 24 bits.

Features

  • 256-channel, current-to-digital converter module Up to 24-bit resolution Variable integration time Fastest integration time: 22.6 kSPS maximum (44.2 μs minimum) at 20-bit resolution Low power dissipation: 2.3 mW per channel at any throughput Integral linearity ±0.050% of reading, ±1.0 ppm of FSR: all channels active Very low noise Simultaneous sampling No dead time, no loss of charge, 100% charge collection User adjustable full-scale range On-board temperature sensor and reference buffer 15 mm ×.
