ADS7038QRTERQ1

Analog To Digital Converters (ADC) Overview

The ADS7038QRTERQ1 is an automotive-grade, 8-channel, multiplexed, 12-bit successive approximation register (SAR) analog-to-digital converter. It supports a maximum sampling rate of 1 MSPS and features an enhanced SPI interface with speeds up to 60 MHz. The device operates with AVDD ranging from 2.35 V to 5.5 V and DVDD from 1.65 V to 5.5 V. It includes programmable averaging filters for 16-bit resolution, a digital window comparator for analog watchdog functions, and built-in cyclic redundancy check (CRC) verification. The component is housed in a 16-pin WQFN package measuring 3 mm x 3 mm.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current orderable addendum to confirm package type and reel specifications. Ensure that the AEC-Q100 qualification grade matches the target automotive application requirements. Confirm availability through authorized distribution channels to guarantee authenticity and traceability.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-channel ADC with mixed-signal I/O capabilities is required. The internal oscillator eliminates the need for external clock sources. Consider the turbo comparator mode if higher comparison rates are needed. Verify that the host system supports the required SPI protocol and CRC verification logic.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7038 family of small, 8-channel, 12-bit SAR ADCs. It shares architectural similarities with the ADS7028 but lacks zero-crossing detection and RMS modules found in other family members. The 'Q1' suffix denotes automotive qualification under AEC-Q100 standards, ensuring reliability for temperature grades extending to 125°C.
