ADS7834E/250

Analog To Digital Converters (ADC) Overview

The ADS7834E/250 is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 500 kS/s and supports differential input signals. The device functions within an analog and digital supply voltage range of 4.75 V to 5.25 V. Key performance metrics include a signal-to-noise ratio of 72 dB, a differential nonlinearity of +/- 0.8 LSB, and an integral nonlinearity of +/- 2 LSB. Power consumption is specified at 11 mW, with a maximum power dissipation of 20 mW. It utilizes an SPI interface for data communication and includes an internal reference. The component is housed in an 8-pin VSSOP package and operates between -40°C and +85°C.
