ADS7952SBDBT

Analog To Digital Converters (ADC) Overview

The ADS7952SBDBT is a 12-bit, 1-MSPS, 12-channel single-ended microPower successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with an analog supply voltage range of 2.7 V to 5.25 V and a digital supply voltage range of 1.7 V to 5.25 V. The device features a serial interface compatible with standard SPI protocols and is housed in a 38-pin Thin-Shrink Small-Outline Package (TSSOP). It supports an operating temperature range from -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to confirm package type and tape-and-reel specifications. Ensure compatibility with required supply voltages and interface logic levels. Confirm RoHS compliance status if environmental regulations apply to the target assembly. Cross-reference the manufacturer's latest datasheet for any pinout or electrical characteristic updates prior to final design integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate resolution, high sampling rate, and multiple input channels is required in a compact surface-mount package. Consider alternative channel counts within the ADS795x family if fewer or more inputs are needed. Evaluate power budget constraints against the specified supply voltage ranges to ensure efficient system operation under varying load conditions.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS795x series of microPower SAR ADCs from Texas Instruments.
