ADS7961SRHBR

Analog To Digital Converters (ADC) Overview

The ADS7961SRHBR is a Texas Instruments analog-to-digital converter featuring an 8-bit resolution and a sampling rate of 1 MSPS. It integrates 12 single-ended input channels within a VQFN-32 package. The device utilizes a Successive Approximation Register (SAR) architecture and communicates via an SPI interface. 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. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 49 dB, a SINAD of 49 dB, and an Integral Nonlinearity (INL) of 0.12% FSR. The component supports an operating temperature range from -40°C to +125°C and consumes 11.5 mW of power.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix SRHBR against the manufacturer's official datasheet to confirm the reel packaging quantity and tape specifications. Ensure compatibility with the target PCB footprint for the VQFN-32 package. Confirm that the external reference voltage requirements align with the system design before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when twelve single-ended inputs are required alongside high-speed 1 MSPS conversion. Compare against the ADS7960 series if differential inputs or higher resolution are needed. Verify that the 8-bit resolution meets the system accuracy requirements and that the SPI interface timing matches the host microcontroller capabilities.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS796x family of low-power, 12-channel ADCs. It shares architectural similarities with the ADS7960 but differs in input configuration. The family is designed for applications demanding multiple channels without sacrificing sampling speed or power efficiency.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7960SRHBR is a pin-compatible alternative within the same family. Verify if the differential input requirement of the ADS7960 conflicts with the single-ended design. Other members of the ADS796x series may offer different resolutions or channel counts but require schematic review.
