ADS7057IRUGR

Analog To Digital Converters (ADC) Overview

The ADS7057IRUGR is a 14-bit, 2.5-MSPS analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a successive approximation register (SAR) architecture and features a single differential input channel. The device operates with an analog supply voltage range of 2.35V to 3.6V and a digital supply voltage range of 1.65V to 3.6V. It communicates via a standard SPI interface and is housed in an 8-X2QFN package measuring 1.5x1.5 mm. The component supports a sampling rate of 2.5 million samples per second and functions within a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix IRUGR corresponds to the required industrial temperature grade and tape-and-reel packaging configuration. Confirm that the analog and digital supply voltages align with the system design constraints before ordering. Ensure compatibility with the target PCB footprint for the 8-X2QFN package during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of high resolution and moderate speed is required alongside automotive qualification. Compare against the ADS7056 if single-ended inputs are sufficient, as it offers similar performance with potentially different input configurations. Consider the ADS7042 if lower resolution and slower speeds meet the application needs while maintaining a similar form factor.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS705x family of ultra-low-power ADCs from Texas Instruments. The family includes variants like the ADS7056 and ADS7057, which share similar architectural traits but differ in input types and specific performance metrics. These devices are designed to replace older, higher-power solutions in portable and automotive sectors.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible alternatives within the same family include the ADS7056IRUGR, though input type differences must be verified. Cross-vendor replacements require careful evaluation of pinout compatibility and electrical parameter matching to ensure seamless integration without circuit redesign.
