Automotive, 8-channel, 140-kSPS, 12-bit analog-to-digital converter (ADC) with I2C, GPIOs and CRC

The ADS7138-Q1 is an easy-to-use,

8-channel, multiplexed, 12-bit, 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

ADC conversion processes.

The ADS7138-Q1 communicates via an

I2C-compatible interface and operates in either autonomous or

single-shot conversion mode. The ADS7138-Q1 implements 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

ADS7138-Q1 has a built-in cyclic redundancy check (CRC) for data read/write

operations and the power-up configuration.
