ADS8508IBDWR

Analog To Digital Converters (ADC) Overview

The ADS8508IBDWR is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a maximum sampling rate of 250 kSPS and supports single-ended input signals. The device features an SPI-compatible serial interface for data output and system control. It 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 (SNR) of 73 dB, differential nonlinearity (DNL) of +/- 0.45 LSB, and integral nonlinearity (INL) of +/- 0.45 LSB. The component is housed in a 20-lead SOIC package and is rated for operation between -40°C and +85°C.
