ADS7954QDBTRQ1 TI ADC | 30-TSSOP | 4-Ch, 12-Bit, 1MSPS

Product Overview

The ADS7954QDBTRQ1 is a 4-channel, 12-bit, 1 MSPS successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It features a unipolar single-ended input, an internal reference, and a serial SPI interface. The device operates from a single 2.7V to 5.25V supply and is specified for the automotive temperature range of -40°C to +125°C. Housed in a 30-pin TSSOP package, this ADC is AEC-Q100 qualified for automotive applications.
