ADS7040IRUGR

Analog To Digital Converters (ADC) Overview

The ADS7040IRUGR is a low-power, ultra-small-size Successive Approximation Register (SAR) Analog-to-Digital Converter manufactured by Texas Instruments. It features an 8-bit resolution and supports a sampling rate of 1 MSPS. The device operates with a single supply voltage ranging from 1.65V to 3.6V for both analog and digital domains. It utilizes a serial Peripheral Interface (SPI) for data communication and accepts single-ended input signals. The component is housed in an 8-X2QFN package measuring 1.5x1.5 mm, suitable for surface-mount installation. It 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 industrial temperature grade and reel packaging configuration required for your assembly line. Confirm that the 8-X2QFN footprint matches your PCB layout guidelines. Ensure compatibility with your SPI controller interface timing specifications before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when 8-bit resolution is sufficient for the application signal chain. Consider alternative models like the ADS7042 or ADS7044 if differential inputs or higher 12-bit resolution are necessary. Verify that the 1 MSPS sampling rate meets the Nyquist criteria for the target input frequency bandwidth.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS704x family of ultra-low-power SAR ADCs from Texas Instruments. The family includes variants with different resolutions and input types, such as the ADS7040 (8-bit), ADS7042 (12-bit single-ended), and ADS7044 (12-bit differential). All share similar low-power characteristics and compact packaging options.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same package include other members of the ADS704x series, such as the ADS7042IRUGR or ADS7044IRUGR, provided resolution and input type differences are acceptable.
