ADS7800KU/1K

Analog To Digital Converters (ADC) Overview

The ADS7800KU/1K is a 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates on a single 5V supply, with both analog and digital power rails ranging from 4.75 V to 5.25 V. The device features a parallel interface and supports a sampling rate of 333 kS/s with a typical sampling time of 3 µs. It includes an internal reference voltage and delivers a signal-to-noise ratio of 73 dB. The component is housed in a 24-pin SOIC package and functions within a temperature range of -40°C to +85°C.
