ADS7866IDBVR – TEXAS INSTRUMENTS

The Texas Instruments ADS7866IDBVR is a 12-bit, successive-approximation register (SAR) analog-to-digital converter (ADC) optimized for low-power applications requiring high accuracy. Packaged in a 16-pin TSSOP (Thin Shrink Small Outline Package), it boasts a typical input voltage range of 0V to VREF, where VREF is externally set, typically between 2.5V and 5V. The device features a single-ended input, simplifying integration, and achieves a maximum conversion rate of 1 MSPS (Mega Samples Per Second). Its low power consumption, typically 1.2mA at 3.3V, makes it ideal for battery-powered systems. Internal sample-and-hold circuitry minimizes input signal variations during conversion._x000D_
