ADS7954SRGET

Analog To Digital Converters (ADC) Overview

The ADS7954SRGET is a 10-bit, 4-channel successive approximation register (SAR) analog-to-digital converter (ADC) from Texas Instruments. It supports single-ended inputs and operates at a sampling rate of 1 MSPS. The device features an SPI-compatible digital interface. 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. Key performance metrics include a signal-to-noise ratio (SNR) of 60 dB and a power consumption of 11.5 mW. Differential nonlinearity (DNL) and integral nonlinearity (INL) are specified at +/- 0.5 LSB. It functions within a temperature range of -40°C to +125°C and is housed in a VQFN-24 package.

Analog To Digital Converters (ADC) Feature Summary

• Four-channel multiplexed input architecture for single-ended signals
• Low-power SAR ADC design with external reference capability
• Flexible dual-supply operation supporting mixed-voltage logic interfaces

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel data acquisition
• Portable instrumentation powered by battery or low-voltage sources
• Automotive sensor interfaces operating under extended temperature conditions

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix SRGET against official datasheets to confirm the reel packaging configuration and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the VQFN-24 package. Confirm that the external reference voltage requirements align with system design constraints before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four single-ended channels are required at 10-bit resolution and 1 MSPS throughput. Compare against the ADS7954SDBT if tube packaging is preferred over reels. Consider the ADS7953 series if higher resolution or additional channels are needed, noting potential differences in pinout and power consumption.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS795x family of micro-power, high-speed SAR ADCs. It shares architectural similarities with other members like the ADS7950 and ADS7953 but differs in resolution and channel count. The SRGET suffix indicates a specific tape-and-reel packaging variant intended for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7954SDBT offers identical electrical specifications but utilizes TSSOP-30 tube packaging instead of the VQFN-24 reel format. Verify footprint compatibility before substitution.
