ADS7953SDBT

Analog To Digital Converters (ADC) Overview

The ADS7953SDBT 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 I/O supply range of 1.7 V to 5.25 V. The device features a serial interface compatible with standard SPI protocols and consumes 11.5 mW of power. It is housed in a 38-pin TSSOP package and supports an operating temperature range from -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Supports high-speed data acquisition with a sampling rate of up to 1 MSPS
• Enables direct interfacing with CMOS digital hosts through wide I/O voltage compatibility

Analog To Digital Converters (ADC) Applications

• Battery-powered systems requiring low power consumption
• Industrial process control and PLC applications
• Medical instrumentation and portable diagnostic devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'SDBT' corresponds to the tube packaging format rather than reel or cut tape options when sourcing components. Confirm that the ordered quantity aligns with the manufacturer's minimum order requirements for tube shipments. Ensure compliance with RoHS directives and lead time expectations during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component for designs requiring multiple single-ended inputs without differential signaling needs. Consider the external reference requirement as the device does not include an internal voltage reference. Evaluate the 12-bit resolution against system accuracy requirements before finalizing the bill of materials.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS795x family of multi-channel SAR ADCs, which also includes variants with 4, 8, and 12 channels. The ADS7953 specifically provides 16 channels, offering higher density compared to the ADS7950 (4-channel) or ADS7951 (8-channel). It shares architectural similarities with the ADS7954 but differs in channel count and pinout configuration.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7953SBDBTR serves as a functional alternative with identical electrical specifications but utilizes reel packaging instead of tubes. Other family members like the ADS7950SDBT offer fewer channels and may require board redesign if channel count reduction is acceptable.
