Overview
The ADS7816PBG4 is a 12-bit, high-speed, micro-power sampling analog-to-digital converter (ADC) produced by Texas Instruments. This device is part of the ADS7816 series and is known for its low power operation, automatic power down, and small size, making it ideal for battery-operated systems and applications where multiple signals need to be acquired simultaneously.
The ADS7816PBG4 features a synchronous serial interface and a differential input, with a reference voltage that can be varied from 100mV to 5V. The converter is based on a successive approximation register (SAR) architecture and includes a sample/hold function, allowing it to acquire and convert analog signals at up to 200,000 conversions per second while consuming very little power.
