ADS7254IRTER

Analog To Digital Converters (ADC) Overview

The ADS7254IRTER is a dual-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a maximum sampling rate of 1 MSPS per channel and supports simultaneous sampling for both inputs. The device utilizes a WQFN-16 package and communicates via an SPI interface. It requires an analog supply voltage between 4.5 V and 5.5 V and a digital supply voltage ranging from 1.65 V to 5.5 V. Key performance metrics include a signal-to-noise ratio of 74 dB and differential input capability.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling architecture ensures precise phase alignment between the two channels.
• Integrated sample-and-hold circuitry provides high-speed data acquisition capabilities.
• Flexible power supply design allows independent optimization of analog and digital domains.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel data acquisition
• Medical instrumentation such as patient monitoring devices
• Vibration analysis and acoustic testing equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRTER indicates tape and reel packaging when sourcing components. Confirm that the ordered part matches the exact ADS7254 model family specifications. Ensure compatibility with existing PCB footprints designated for the WQFN-16 package type during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous dual-channel conversion at 12-bit resolution is required. Compare against the ADS7253 if single-ended or pseudo-differential inputs are acceptable instead of strictly differential signals. Evaluate the ADS7250 if a lower sampling rate of 750 kSPS suffices for the application requirements.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS725x series of low-power, high-speed SAR ADCs from Texas Instruments. It shares architectural similarities with the ADS7250 and ADS7253 but distinguishes itself through its support for fully differential inputs across both channels while maintaining the same 1 MSPS throughput.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7254IRTET serves as a parameter-equivalent alternative offering identical electrical characteristics in a tray package format. Designers may also consider the ADS7253 for applications where single-ended input flexibility is prioritized over strict differential signaling requirements.
