ADS7953SBDBTR

Analog To Digital Converters (ADC) Overview

The ADS7953SBDBTR is a 12-bit, 1-MSPS, 16-channel single-ended microPower SAR 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 peripheral interface (SPI) for data communication. Key performance metrics include a signal-to-noise ratio (SNR) of 70 dB, differential nonlinearity (DNL) of +/- 1 LSB, and integral nonlinearity (INL) of +/- 1 LSB. Power consumption is specified at 11.5 mW. It functions within a temperature range of -40°C to +125°C and is housed in a 38-pin TSSOP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging configuration. Confirm that the component meets RoHS compliance requirements for the intended market. Check for moisture sensitivity level ratings relevant to surface mount assembly processes. Ensure the TSSOP-38 footprint matches the design layout specifications before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of moderate resolution and high channel count is required for single-ended signals. Consider the external reference requirement as the device does not integrate an internal voltage reference. Evaluate the SPI interface compatibility with the host microcontroller or DSP. Compare power dissipation limits against available thermal management solutions in the target enclosure.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7953 family of microPower SAR ADCs from Texas Instruments. It shares core architectural similarities with variants such as the ADS7953SDBTR and ADS7953SBRHBT, differing primarily in package type and reel configuration. The SBDBTR designation specifically indicates the TSSOP-38 package with tape-and-reel delivery. Other family members may offer different pin counts or channel configurations.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include ADS7953SDBTR and ADS7953SBDBTG4, which share identical electrical specifications and pinouts. Cross-package alternatives like ADS7953SRHBT require schematic and PCB layout modifications due to the VQFN-32 form factor. Verify pin compatibility and thermal performance when considering these options.
