Overview
The ADS7886SBDBVR is a 12-bit, 1-MSPS analog-to-digital converter (ADC) produced by Texas Instruments. This device features a capacitor-based Successive Approximation Register (SAR) A/D converter with inherent sample and hold circuitry. It is designed for low power consumption, making it suitable for battery-powered applications. The ADS7886 operates over a wide supply range from 2.35 V to 5.25 V and includes a power-down feature for additional power savings at lower conversion speeds. The device is available in 6-pin SOT-23 and SC70 packages and is specified for operation from –40°C to 125°C.
