ADS7842E TI Analog-to-Digital Converter | 28-SSOP | 12-Bit, 8-Channel

Product Overview

The ADS7842E from Texas Instruments is a 12-bit, 8-channel successive approximation analog-to-digital converter (ADC) featuring a serial interface and a maximum sampling rate of 200 kSPS. It operates from a single +5V supply and includes an internal 2.5V reference. The device is housed in a compact 28-pin SSOP package, making it ideal for space-constrained applications requiring high accuracy and low power consumption.
