ADS7250IRTER

Analog To Digital Converters (ADC) Overview

The ADS7250IRTER 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 signal-to-noise ratio is specified at 73 dB. The component functions reliably within an industrial temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRTER against official Texas Instruments documentation to confirm tape-and-reel packaging specifications. Ensure that the ordered quantity aligns with standard reel sizes defined in the manufacturer's shipping guidelines. Cross-reference the date code and lot number upon receipt to maintain traceability standards required for regulated industries. Confirm RoHS compliance status matches current environmental regulations applicable to your region before finalizing procurement contracts.

Analog To Digital Converters (ADC) Selection Notes

Select this component when simultaneous sampling of two channels is critical for phase-sensitive applications. The pseudo-differential input structure offers improved noise immunity compared to single-ended configurations without requiring complex differential driver circuits. Verify that the system clock frequency supports the desired 750 kSPS throughput while maintaining signal integrity across the PCB layout. Consider the thermal performance of the WQFN package if operating near the upper limit of the specified temperature range.

Analog To Digital Converters (ADC) Part Context

The ADS7250 belongs to the broader ADS725x family of low-power, high-speed SAR ADCs from Texas Instruments. This series shares common architectural features such as the internal track-and-hold amplifier and reference buffer. Variants within the family typically differ in sampling rates or input configurations, making the ADS7250 distinct due to its specific 750 kSPS rating and pseudo-differential input capability designed for cost-effective dual-channel solutions.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7250IRTET serves as a tube-packaged equivalent offering identical electrical characteristics. For higher throughput requirements, the ADS7251 provides a 2 MSPS sampling rate with similar pinout compatibility. Engineers should verify pin-to-pin compatibility and software register settings when migrating between these variants to ensure seamless integration into existing designs.
