ADS7250IRTET

Analog To Digital Converters (ADC) Overview

The ADS7250IRTET 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 750 kSPS and features simultaneous sampling capabilities for both channels. The device utilizes a 16-pin WQFN package and supports SPI digital interfaces. It requires an analog supply voltage ranging from 4.5 V to 5.5 V and a digital supply voltage between 1.65 V and 5.5 V. The input configuration is pseudo-differential, and the unit functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Feature Summary

• Simultaneous sampling architecture ensures precise phase alignment between two independent channels.
• Pseudo-differential input structure provides improved noise rejection compared to single-ended configurations.
• Flexible power supply design allows separate optimization of analog and digital domains.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring synchronized multi-channel data acquisition
• Vibration monitoring and acoustic emission analysis in machinery health diagnostics
• Medical instrumentation utilizing differential signal paths for high-fidelity biological signals

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRTET' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the industrial temperature grade (-40°C to +125°C) meets the operational environmental constraints of the target application. Ensure compatibility with the system's SPI clock speeds and voltage levels before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of two channels is critical for maintaining signal integrity. The 12-bit resolution and 750 kSPS speed balance precision with throughput requirements. Consider the pseudo-differential input type if ground loops are a concern but full differential drivers are unavailable. Verify that the WQFN-16 footprint fits the PCB layout constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS725x family of low-power, simultaneous-sampling ADCs. It shares architectural similarities with the ADS7251, ADS7253, and ADS7254, differing primarily in sampling rates and input types. While the ADS7251 offers higher speed and the ADS7253/ADS7254 provide alternative input configurations, the ADS7250 specifically targets applications needing moderate speed with pseudo-differential inputs.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7251IRTET serves as a parameter-equivalent alternative with a higher 2 MSPS sampling rate but maintains the same 12-bit resolution and package. Designers must verify if the increased speed impacts power consumption or if the system timing can accommodate the faster conversion cycle without modification.
