ADS1260BIRHBR

Overview

The ADS1260BIRHBR is a 24-bit, 5-channel delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It features an integrated multiplexer, programmable gain amplifier (PGA), and internal reference. The device supports differential or single-ended inputs with a maximum sampling rate of 40 kSPS. It operates on a 5 V analog supply and a digital supply ranging from 2.7 V to 5.25 V. Communication is handled via an SPI interface. The component is housed in a 32-pin VQFN package and is rated for operation between -40°C and +125°C.

Feature Summary

• Integrates a 5-channel multiplexer and programmable gain amplifier for direct sensor interfacing
• Includes built-in excitation current sources (iDACs) for bridge sensor biasing
• Features internal oscillator and temperature sensor for system monitoring
• Provides high noise rejection capabilities for power line frequencies

Applications

• Industrial process control systems requiring multi-channel data acquisition
• Weigh scales and load cell measurement applications
• Thermocouple and RTD temperature measurement instrumentation
• Medical equipment signal conditioning

Procurement Notes

Verify the specific suffix against official documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating voltage ranges and interface protocols before integration. Confirm RoHS compliance status through manufacturer datasheets.

Selection Notes

Select this model when five independent channels are required within a single ADC unit. Consider the ADS1261 variant if ten channels are needed instead. Verify that the 32-VQFN package dimensions fit the target PCB layout constraints.

Part Context

This component belongs to the ADS126x family of precision ADCs designed for low-noise, high-resolution measurements. It shares architectural similarities with other devices in the series but is distinguished by its specific five-channel configuration and integrated signal chain components.

Replacement Considerations

ADS1260BIRHBT is listed as a parameter-equivalent alternative offering identical electrical characteristics with a different packaging format.
