ADS7835E/250

Analog To Digital Converters (ADC) Overview

The ADS7835E/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 single-ended input signals via an SPI-compatible digital interface. 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, differential nonlinearity of +/- 0.8 LSB, and integral nonlinearity of +/- 2 LSB. Power consumption is rated at 17.5 mW typical, with a maximum power dissipation of 30 mW. It is housed in an 8-pin VSSOP package measuring 3 mm x 3 mm x 0.97 mm.
