ADC122S021CIMM/NOPB TI 12-Bit ADC | 8-VSSOP | 2-Ch, 200ksps, SPI

Product Overview

The ADC122S021CIMM/NOPB is a low-power, two-channel CMOS 12-bit analog-to-digital converter from Texas Instruments. It operates from a single 2.7V to 5.25V supply and features a successive approximation register (SAR) architecture. The device includes a 2-channel input multiplexer, a track-and-hold amplifier, and a serial interface compatible with SPI. The conversion rate is up to 200 ksps. The ADC122S021CIMM/NOPB is offered in an 8-lead VSSOP package, making it suitable for space-constrained applications.
