ADS7956SRHBT

Analog To Digital Converters (ADC) Overview

The ADS7956SRHBT 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 and is housed in a 32-pin VQFN package. Key performance metrics include a signal-to-noise ratio (SNR) of 71.7 dB and a signal-to-noise and distortion ratio (SINAD) of 71.3 dB. The integral nonlinearity (INL) is specified at 0.024% FSR. Power consumption is rated at 11.5 mW, and it supports an operating temperature range from -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'SRHBT' to confirm the reel packaging format and tape-and-reel quantity. Ensure compatibility with the required operating temperature range of -40°C to +125°C for your application environment. Confirm that the external reference voltage matches the device's input requirements. Check for moisture sensitivity level compliance during storage and handling procedures.

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. Compare against the ADS7953 for identical electrical specifications but different packaging options. Consider the ADS7957 if lower resolution is acceptable for reduced cost. Evaluate the ADS7960 if fewer channels are sufficient for the design constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS795x family of microPower SAR ADCs from Texas Instruments. The family shares common architectural features including 1 MSPS sampling rates and SPI interfaces. Variations within the series primarily differ in resolution (8-bit, 10-bit, 12-bit) and channel counts (4, 8, 12, 16). The SRHBT designation indicates a specific thermal and packaging variant within this product line.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7953SRHBR offers equivalent electrical performance in a similar VQFN-32 package but may differ in reel packaging quantities. ADS7953SDBT provides the same functionality in a TSSOP-38 package, requiring PCB layout adjustments. No direct pin-compatible substitutes exist with different resolutions without circuit redesign.
