ADS7829IBDRBR

Analog To Digital Converters (ADC) Overview

The ADS7829IBDRBR is a single-channel, 12-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 5.25 V for both analog and digital domains. The device features a pseudo-differential input architecture and communicates via a 3-wire synchronous serial interface compatible with standard SPI protocols. It supports a maximum sampling rate of 125 kSPS and is housed in an 8-pin SON package. The component is rated for operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Supports flexible 3-wire synchronous serial communication interfaces
• Operates efficiently across a wide single-supply voltage range

Analog To Digital Converters (ADC) Applications

• Portable instrumentation systems requiring low power consumption
• Battery-powered data acquisition modules
• Industrial process control signal conditioning

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'RG4' or 'R' against the manufacturer's current datasheet to confirm tape-and-reel packaging specifications and RoHS compliance status. Ensure the ordered part number matches the exact industrial temperature grade and pinout configuration required for the target PCB layout. Cross-reference the manufacturer's official ordering guide to validate availability and lead times directly from the source.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a balance of 12-bit resolution and moderate speed is required for single-channel conversion tasks. Compare performance metrics such as differential nonlinearity and total unadjusted error against alternative SAR ADCs in the same family. Confirm that the pseudo-differential input range aligns with the sensor output characteristics before finalizing the design.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS782x series of low-power, 12-bit ADCs from Texas Instruments. It shares architectural similarities with the ADS7826 and ADS7827 but offers higher resolution. The device is designed to replace older parallel or slower serial ADCs in space-constrained designs utilizing the compact SON-8 footprint.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS7829IDRBR is a direct functional equivalent with commercial temperature grading. The ADS7829IDRBT serves as an alternative if cut-tape packaging is preferred over reel packaging. Verify pin compatibility when substituting with other members of the ADS782x family.
