ADS7950SBDBT

Analog To Digital Converters (ADC) Overview

The ADS7950SBDBT is a 12-bit, 4-channel successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It operates with a sampling rate of 1 MSPS and supports single-ended inputs. The device features an SPI-compatible serial interface for data output. It requires an external voltage reference, typically set to 2.51 V. Power consumption is specified at 11.5 mW. The analog supply voltage ranges from 2.7 V to 5.25 V, while the digital supply voltage ranges from 1.7 V to 5.25 V. The component is housed in a 30-pin TSSOP package and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Micro-power architecture enabling low energy consumption during operation
• Single-ended input configuration suitable for various sensor interfaces
• External reference input capability for flexible voltage scaling

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel data acquisition
• Portable instrumentation powered by battery sources
• Data logging applications with moderate speed requirements

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'SBDBT' against the manufacturer's official datasheet to confirm pinout compatibility and package dimensions. Ensure that the external reference voltage matches the required 2.51 V specification for optimal performance. Confirm RoHS compliance status through the official documentation before integration into regulated assemblies.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four single-ended channels are required at 12-bit resolution and 1 MSPS throughput. Compare against the ADS7953 if sixteen channels are needed or the ADS7960 if eight-bit resolution suffices. Verify that the system power rails align with the separate analog and digital supply voltage ranges defined in the specifications.

Analog To Digital Converters (ADC) Part Context

This part belongs to the microPOWER ADC family from Texas Instruments, designed for low-power data conversion tasks. It shares architectural similarities with other members like the ADS7951 and ADS7953, differing primarily in channel count and package options. The series emphasizes efficiency for battery-operated devices without sacrificing significant accuracy.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7953SBDBT offers similar performance but provides 16 channels instead of 4. The ADS7955SDBT provides 8 channels with 10-bit resolution. Verify pin compatibility and software register settings when substituting these variants.
