Overview
The ADS7866IDBVTG4 is a 12-bit, low-power, miniature analog-to-digital converter (ADC) produced by Texas Instruments. This device is part of the ADS7866 family, which includes 12-bit, 10-bit, and 8-bit versions. The ADS7866IDBVTG4 operates from a single supply voltage ranging from 1.6 V to 3.6 V and can maintain a throughput of up to 200 KSPS. It features a unipolar, single-ended input and is characterized over the industrial temperature range of –40°C to 85°C.
This ADC is packaged in a 6-pin SOT-23 package, making it suitable for space-constrained applications. It includes auto power-down functionality, which significantly reduces power consumption when the device is not actively converting, making it ideal for battery-powered systems and other power-sensitive applications.
