ADS7863IRGET

Analog To Digital Converters (ADC) Overview

The ADS7863IRGET is a dual 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates within an analog and digital supply voltage range of 2.7 V to 5.5 V. The device supports sampling rates up to 1 MS/s with a signal-to-noise ratio of 71.5 dB. It features differential or pseudo-differential input types and communicates via an SPI interface. Key linearity specifications include a differential nonlinearity of +/- 1 LSB and an integral nonlinearity of +/- 1.25 LSB. The component is housed in a 24-VQFN package and functions reliably across a temperature range of -40°C to +125°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to confirm package type and tape/reel configuration. Check current lifecycle status as components may be marked as not recommended for new designs. Confirm moisture sensitivity level requirements for your manufacturing process. Ensure compatibility with existing SPI bus protocols and voltage levels. Review datasheet revisions for any recent parameter updates before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this model when dual-channel simultaneous sampling at 12-bit resolution is required. Consider the 2.7 V to 5.5 V supply range for system power budgeting. Evaluate the 24-VQFN package dimensions against PCB space constraints. Compare the 1 MS/s sampling rate against application bandwidth needs. Verify thermal performance within the -40°C to +125°C operating range.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADS7863 series of high-speed, low-power ADCs from Texas Instruments. It shares architectural similarities with other SAR-based converters but offers specific channel configurations and interface options. The IRGET suffix indicates a specific tape and reel packaging variant intended for automated surface-mount assembly processes.

Analog To Digital Converters (ADC) Replacement Considerations

Check for ADS7863 variants with different suffixes that may offer alternative packaging or updated lifecycle statuses. Verify functional pinouts and electrical parameters against potential substitutes to ensure direct compatibility without circuit redesign.
