ADS7844E/2K5 TI Analog to Digital Converters | 20-SSOP | 12-Bit, 8-Channel

Product Overview

The ADS7844E/2K5 is a high-performance, 12-bit, 8-channel analog-to-digital converter (ADC) from Texas Instruments. It features a successive approximation register (SAR) architecture with a maximum sampling rate of 200 kSPS. The device operates from a single 2.7V to 5.25V supply and includes an internal 2.5V reference. Housed in a compact 20-SSOP package, it is ideal for space-constrained applications requiring multiple analog inputs.
