ADS7280IRSAR

Analog To Digital Converters (ADC) Overview

The ADS7280IRSAR is a dual-channel, 16-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with an analog supply voltage range of 4.5V to 5.5V and a digital supply voltage range of 1.65V to 5.5V. The device supports sampling rates up to 1MSPS per channel and features a serial peripheral interface (SPI) compatible with DSP systems. It is housed in a 20-pin WQFN package with exposed pad for surface-mount installation.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IRSAT' against the manufacturer's official datasheet to confirm temperature grade and packaging details. Ensure compatibility with system power supplies and SPI timing requirements before integration. Check for RoHS compliance status as indicated in the latest documentation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel 16-bit resolution is required at speeds up to 1MSPS. Compare performance metrics such as SNR and THD against alternative SAR ADCs if higher resolution or lower noise is needed. Consider the WQFN package size constraints during PCB layout design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7280 family of high-speed, high-resolution data converters. It shares architectural similarities with other devices in the series but offers specific pinout and performance characteristics tailored for dual-channel applications. The 'IR' designation typically indicates industrial temperature range operation.

Analog To Digital Converters (ADC) Replacement Considerations

ADS7280IRTET is a parameter-equivalent alternative from Texas Instruments offering the same electrical specifications in a different tape-and-reel packaging format.
