Overview
The ADS7816EB/2K5G4 is a 12-bit, high-speed, micro-power sampling analog-to-digital converter (ADC) produced by Texas Instruments. This device is designed for low power operation and features automatic power down, making it ideal for battery-operated systems and applications where multiple signals need to be acquired simultaneously. The ADS7816 uses a successive approximation register (SAR) architecture based on capacitive redistribution, which includes a sample/hold function, allowing it to convert analog signals at up to 200,000 conversions per second while consuming minimal power.
