Automotive, 8-channel, 1-MSPS, 12-bit analog-to-digital converter (ADC) with SPI, GPIOs and CRC

The ADS7038-Q1 is an easy-to-use,

8-channel, multiplexed, 12-bit, 1-MSPS, successive approximation register

analog-to-digital converter (SAR ADC). The eight channels can be independently

configured as either analog inputs, digital inputs, or digital outputs. The device has

an internal oscillator for the ADC conversion process.

The ADS7038-Q1 communicates through an

SPI-compatible interface and operates in either autonomous or single-shot conversion

mode. The ADS7038-Q1 implements the analog watchdog function by event-triggered

interrupts per channel using a digital window comparator with programmable high and

low thresholds, hysteresis, and an event counter. The ADS7038-Q1 has a built-in

cyclic redundancy check (CRC) for data read/write operations and the power-up

configuration.
