ADS7863IRGER

Analog To Digital Converters (ADC) Overview

The ADS7863IRGER is a dual-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate of 1 MSPS and supports both differential and pseudo-differential input configurations. The device integrates an internal reference and features an SPI-compatible digital interface. It functions within an analog and digital supply voltage range of 2.7 V to 5.5 V. Key performance metrics include a signal-to-noise ratio of 71.5 dB, a differential nonlinearity of +/- 1 LSB, and an integral nonlinearity of +/- 1.25 LSB. The component is housed in a 24-pin VQFN package and is rated for operation between -40°C and +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'GER' against the official datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Check for obsolescence notices as this part may be designated as not recommended for new designs depending on the current date relative to the manufacturer's lifecycle announcements.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel simultaneous sampling at 1 MSPS is required with 12-bit resolution. Ensure the system voltage aligns with the 2.7 V to 5.5 V operating range. Consider the VQFN-24 package constraints for PCB layout. Compare against the ADS7863ARGET if a higher 2 MSPS sampling rate is needed, noting that the IRGER variant is specified for 1 MSPS operation.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADS7863 family of low-power, 12-bit SAR ADCs from Texas Instruments. It shares architectural similarities with other members like the ADS7862 and ADS7864 but differs in channel count, interface type, and maximum sampling speed. The IRGER designation specifically identifies the industrial temperature grade version in the VQFN package.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7863ARGET is a functional upgrade within the same series offering 2 MSPS sampling speed. Verify pin compatibility and software register settings before substitution. Other family members like the ADS7862 offer parallel interfaces which require significant hardware redesign.
