Overview
The ADS7842E/1K is a 12-bit, 4-channel analog-to-digital converter (ADC) manufactured by Texas Instruments. This device is designed for high-performance data acquisition and features a successive approximation register (SAR) architecture with a sample-and-hold amplifier. It operates from a single supply voltage ranging from 2.7V to 5.25V and is available in an SSOP-28 package. The ADS7842E/1K is ideal for applications requiring low power consumption and high-speed sampling, making it suitable for battery-operated systems, portable data loggers, and various measurement equipment.
