The ADS7816UB/2K5 is a 12-bit, ultra-small, low-power single-channel, analog-to-digital converter (ADC) from Texas Instruments. This integrated circuit is part of TI's precision ADC family, designed for applications where space and power efficiency are critical. With a sampling rate of up to 200K samples per second, this ADC provides a convenient balance between speed and resolution, making it suitable for battery-operated devices, portable instruments, and other systems where power consumption must be minimized. Operating from a single 2.7V to 5.5V power supply, it offers a versatile solution for converting analog signals into digital data in multiple applications. The 2K5 suffix identifies the device's packaging option and order quantity, indicating this part is offered in a compact MSOP (Micro Small Outline Package) and typically sold in reels of 2500 units. This ADC is widely used in sensor interfacing, data acquisition systems, and digital signal processing where space, power, and accuracy are paramount.
