ADS7251IRTER

Analog To Digital Converters (ADC) Overview

The ADS7251IRTER 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 2 MSPS and features simultaneous sampling capabilities for both channels. The device utilizes a 16-WQFN package measuring 3x3 mm. It supports an analog supply voltage of 5V and a digital supply range of 1.65V to 5.25V. Input types are differential, and the data interface is serial. The component 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 input channels.
• Integrated sample-and-hold circuitry maintains signal integrity during conversion cycles.
• Flexible digital interface compatibility allows operation across varying logic voltage levels.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring high-speed multi-channel data acquisition
• Medical instrumentation utilizing differential signal inputs
• Automotive sensor interfaces demanding wide operating temperature ranges

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'TER' indicates tape and reel packaging when ordering. Confirm that the analog supply requirements align with standard 5V systems. Ensure the digital interface voltage matches the target system's logic level, as it supports a wide range from 1.65V to 5.25V. Check for RoHS compliance status if required by project specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this model when simultaneous sampling of two differential signals at up to 2 MSPS is required. Compare against the ADS7250IRTET if a lower sampling rate of 750 kSPS is sufficient for the application. Consider the ADS7851IRTER if higher 14-bit resolution is necessary instead of 12-bit precision. Verify package availability in tape and reel format for automated assembly.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS725x family of dual-channel SAR ADCs from Texas Instruments. It shares the same 16-WQFN footprint and pinout configuration with other members like the ADS7250 and ADS7253. The primary distinction lies in the sampling speed, with this variant offering the highest throughput in its immediate series group.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7251IRTET is a parameter-equivalent alternative available in cut tape or tube formats. Both variants share identical electrical specifications and functionality. Choose based on preferred packaging method for manufacturing processes.
