ADS7953SBDBT

Analog To Digital Converters (ADC) Overview

The ADS7953SBDBT 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 SPI interface and consumes 11.5 mW of power. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 70 dB and a SINAD of 71.3 dB. Differential Nonlinearity (DNL) and Integral Nonlinearity (INL) are specified at +/- 1 LSB. 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) Feature Summary

• Provides 16 single-ended analog input channels for multi-point data acquisition.
• Integrates a successive approximation register (SAR) architecture with built-in sample-and-hold functionality.
• Supports zero-latency conversion sequences via a high-speed serial interface.

Analog To Digital Converters (ADC) Applications

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

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BDBTR' corresponds to the TSSOP-38 package and reel packaging configuration. Confirm RoHS compliance status and humidity sensitivity level prior to assembly. Ensure the external reference voltage matches the required 2.51 V specification for optimal linearity performance.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 16 single-ended channels are required alongside 12-bit resolution at 1 MSPS. Compare against ADS7950 for fewer channels or ADS7954 for lower resolution options. Verify that the host system supports the required 1.7 V to 5.25 V digital logic levels for seamless integration.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS795x family of microPower SAR ADCs from Texas Instruments. It shares architectural similarities with the ADS7950, ADS7951, and ADS7954, differing primarily in channel count and resolution. The SBDBT suffix indicates the specific TSSOP-38 package variant within this series.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7953SDBTR serves as the tube-packaged equivalent. For fewer channels, consider ADS7950SBDBT (4-channel). For lower resolution needs, ADS7954SDBT (10-bit, 4-channel) is available. Cross-reference pinouts carefully when substituting packages.
