ADS7955SRGET

Analog To Digital Converters (ADC) Overview

The ADS7955SRGET is a Texas Instruments microPOWER SAR ADC featuring 10-bit resolution and an 8-channel single-ended input multiplexer. It operates at a sampling rate of 1 MSPS with an SPI digital interface. The device supports analog supply voltages from 2.7 V to 5.25 V and digital supplies from 1.7 V to 5.25 V. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 60 dB, a SINAD of 60 dB, and an Integral Nonlinearity (INL) of 0.048% FSR. Power consumption is rated at 11.5 mW. It is housed in a VQFN-24 package and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel single-ended input multiplexer with a successive approximation register architecture for efficient multi-point data acquisition.
• Supports flexible power configurations with independent analog and digital supply voltage ranges to accommodate various system logic levels.
• Provides high linearity performance with specified integral nonlinearity characteristics suitable for precision measurement applications.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation requiring low power consumption and multiple analog inputs
• Industrial process control systems utilizing serial communication interfaces
• Data acquisition modules for battery-operated devices

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'GET' corresponds to the VQFN-24 package and reel packaging configuration as listed in the official datasheet. Confirm that the external reference voltage requirement aligns with the target application's precision needs, as this device does not include an internal reference. Ensure compatibility with the host controller's SPI mode and voltage levels before integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when eight single-ended channels are required alongside moderate resolution and speed. Compare against the ADS7955SDBT if a TSSOP-30 package is preferred for through-hole or different surface mount constraints. Consider the ADS7947SRTER if differential inputs or higher resolution are necessary instead of the current single-ended 10-bit specification.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Texas Instruments microPOWER family of analog-to-digital converters. It shares architectural similarities with other members like the ADS7950 and ADS7953 but is distinguished by its 10-bit resolution and eight-channel capacity. The series is designed for applications balancing power efficiency with sufficient throughput for general-purpose sensing tasks.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7955SDBTR is a tape-and-reel alternative in a TSSOP-30 package. ADS7955SRGER offers the same electrical specifications in a VQFN-24 package with different reel quantities. Verify pinout compatibility and thermal performance when substituting between package types.
