ADS1260BIRHBT

Overview

The ADS1260BIRHBT is a 24-bit, 5-channel delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates with a maximum sampling rate of 40 kSPS and supports both differential and single-ended input configurations. The device integrates a programmable gain amplifier (PGA), internal oscillator, temperature sensor, and excitation current sources (iDACs). It features 50/60 Hz rejection capabilities and accepts external or internal reference voltages. Power consumption is rated at 24 mW, with an analog supply voltage of 5 V and digital supply ranging from 2.7 V to 5.25 V. The component is housed in a 32-pin VQFN package and functions within a temperature range of -40°C to +125°C.

Feature Summary

• Integrates five independent channels with dedicated multiplexers and programmable gain amplifiers for flexible signal conditioning.
• Includes built-in excitation current sources suitable for driving resistive sensors such as RTDs and strain gauges.
• Features integrated hardware filters providing inherent rejection of power line interference frequencies.

Applications

• Industrial process control systems requiring high-precision multi-channel data acquisition
• Weigh scales and load cell measurement instrumentation
• Thermocouple and resistance temperature detector (RTD) monitoring

Procurement Notes

Verify the specific suffix 'BIRHBT' against the manufacturer's latest datasheet to confirm pinout compatibility and electrical specifications. Ensure that the ordering documentation matches the exact part number to avoid receiving variants with different packaging or performance characteristics. Cross-reference the component marking with official identification guides to prevent counterfeit substitution during procurement.

Selection Notes

Select this component when a system requires five simultaneous high-resolution measurements without external multiplexing. Compare channel count requirements against the ADS1261 variant if ten channels are needed instead of five. Evaluate the need for integrated iDACs and PGA functionality to determine if external signal conditioning components can be eliminated from the design.

Part Context

This device belongs to the ADS126x family of precision ADCs designed for industrial applications. It shares architectural similarities with the ADS1261 but differs in channel density. The family utilizes sigma-delta modulation to achieve high resolution and low noise performance. It serves as a direct replacement for older discrete solutions in high-end measurement equipment.

Replacement Considerations

The ADS1260BIRHBR is a parameter-equivalent alternative available in tape-and-reel packaging. Verify package compatibility and reflow soldering profiles when substituting between cut-tape and reel formats. No other functional substitutes are documented in the provided source material.
