ADS7950SBDBTR

This is a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It offers a maximum sample rate of 1 MSPS and features four multiplexed single-ended input channels. The device uses an SPI serial interface for communication.

The ADC operates with an external reference and supports an input voltage range of 0 V to 5.25 V. It requires an analog supply voltage from 2.7 V to 5.25 V and a separate digital I/O supply from 1.7 V to 5.25 V. Typical power consumption is 11.5 mW, and the device achieves a signal-to-noise ratio (SNR) of 71.7 dB.

The ADS7950SBDBTR is part of the ADS79xx family of pin-compatible ADCs. It is designed for precision data acquisition applications requiring low power and small footprint. The device includes features such as auto and manual channel selection, two programmable alarm levels per channel, and four configurable GPIOs (in the TSSOP package).

The device is available in a 30-pin TSSOP package (30-TFSOP, 0.173" width, 4.40mm) and is surface-mountable. It operates over an industrial temperature range of -40°C to 125°C. The package is also footprint-compatible with 8- and 16-channel variants of the same family.
