ADS7956SDBTR

Analog To Digital Converters (ADC) Overview

The ADS7956SDBTR is a 12-bit, 1-MSPS, 8-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 I/O supply 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 TSSOP package. It supports an operating temperature range from -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel multiplexer with a sample-and-hold circuit for efficient multi-point data acquisition.
• Utilizes a SAR architecture to achieve high-speed conversion rates up to 1 MSPS with low power consumption.
• Supports flexible digital interface connections through independent analog and digital supply domains.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal monitoring
• Portable instrumentation powered by battery or low-voltage sources
• Data acquisition modules in harsh environmental conditions

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'SDBTR' corresponds to the tape-and-reel packaging format intended for automated assembly processes. Confirm that the component meets RoHS compliance standards and check for moisture sensitivity level ratings relevant to your reflow soldering profile requirements before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this model when eight single-ended input channels are required at 12-bit resolution. Ensure the system design accommodates the separate analog and digital supply voltages if noise isolation is critical. Compare channel count against alternatives like the ADS7953 if more inputs are needed, or the ADS7950 if fewer channels suffice.

Analog To Digital Converters (ADC) Part Context

This component belongs to the Texas Instruments ADS795x family of microPower ADCs. It shares architectural similarities with the ADS7950 and ADS7953 but is distinguished by its specific eight-channel configuration. The family is designed for applications balancing speed, resolution, and power efficiency in compact surface-mount packages.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7956SDBTG4 is a lead-free variant within the same series. Verify pin compatibility and electrical specifications against the ADS7950 or ADS7953 if channel count adjustments are permissible in the design.
