ADS7950SDBT

Analog To Digital Converters (ADC) Overview

The ADS7950SDBT is a 12-bit, 4-channel successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with a sampling rate of 1 MSPS and supports single-ended inputs via an SPI interface. The device functions within an analog supply voltage range of 2.7 V to 5.25 V and a digital supply range of 1.7 V to 5.25 V. Key performance metrics include a signal-to-noise ratio (SNR) of 71.7 dB and a total power consumption of 11.5 mW. Differential nonlinearity (DNL) is specified at -2/1.5 LSB, while integral nonlinearity (INL) is +/- 1.5 LSB. It is housed in a 30-pin TSSOP package and rated for operation between -40°C and +125°C.
