Overview
The ADS7866IDBVT is a 12-bit analog-to-digital converter (ADC) produced by Texas Instruments. This device is part of the ADS7866/67/68 family, known for their low power consumption and high throughput. The ADS7866IDBVT operates from a single supply voltage ranging from 1.2 V to 3.6 V and features a unipolar, single-ended input. It is designed for high-speed applications, interfacing with microprocessors or DSPs through a high-speed SPI compatible serial interface. The device is packaged in a compact 6-pin SOT-23 package and is characterized over the industrial temperature range of -40°C to 85°C.
