ADS7822IDGKRQ1

Analog To Digital Converters (ADC) Overview

The ADS7822IDGKRQ1 is a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) designed for automotive applications. It features a sampling rate of 200 kSPS and operates with an analog supply voltage range of 2.7 V to 5.25 V. The device utilizes a 3-wire serial interface compatible with standard protocols. It supports pseudo-differential or single-ended input configurations. Key performance metrics include a differential nonlinearity (DNL) of ±2 LSB and an integral nonlinearity (INL) of ±2 LSB. The SINAD is specified at 71 dB, with a typical power consumption of 1.6 mW. It is housed in an 8-pin VSSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RQ1' confirms automotive grade status and tape-and-reel packaging. Confirm the manufacturer source directly from Texas Instruments documentation. Ensure the component meets AEC-Q100 reliability requirements for your specific application environment. Check for any specific handling instructions related to moisture sensitivity levels.

Analog To Digital Converters (ADC) Selection Notes

Select this component when automotive certification is mandatory for high-speed data acquisition. Compare DNL/INL specifications against system accuracy requirements. Evaluate the 2.7V minimum supply constraint against available power rails. Consider the VSSOP-8 package size for PCB layout constraints relative to other SAR ADCs.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7822 family of microPower sampling ADCs. It shares core architectural similarities with the commercial ADS7822 but includes enhanced reliability testing for automotive environments. The 'DGK' indicates the VSSOP-8 package type, while 'RQ1' denotes the automotive grade and reel packaging configuration within the Texas Instruments portfolio.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7822IDGKT: Commercial grade equivalent without automotive qualification. ADS7822EVM: Evaluation module for development, not a direct replacement. Verify pin compatibility and software interface compatibility when substituting with other 12-bit SAR ADCs.
