ADS125H01IRHBR

Overview

The ADS125H01IRHBR is a single-channel, 24-bit 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 utilizes an SPI interface for digital communication. Power requirements include an analog supply voltage range of 4.75 V to 5.25 V and a digital supply voltage range of 2.7 V to 5.25 V. Key performance metrics include a gain error of 0.1% and an integral nonlinearity (INL) of 4 PPM FSR. The component is housed in a VQFN-32 package and functions within a temperature range of -30°C to +125°C.

Feature Summary

• 24-bit resolution with 40 kSPS sampling speed
• Integrated programmable gain amplifier (PGA)
• Built-in 50/60 Hz rejection filter capability
• Internal oscillator for simplified system design

Applications

• Industrial process control systems
• Weigh scales and load cell measurements
• High-resolution sensor data acquisition

Procurement Notes

Verify the specific suffix 'IRHBR' corresponds to the VQFN-32 package and reel packaging format. Confirm RoHS compliance status through official manufacturer documentation. Ensure the operating environment stays within the specified -30°C to +125°C temperature range. Check for moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component when a single high-resolution channel is required at moderate speeds. The integrated PGA reduces external component count compared to discrete solutions. Consider the power dissipation of 79 mW for thermal management. Verify that the SPI interface timing meets the host microcontroller's capabilities.

Part Context

This part belongs to the ADS125H01 series, designed for precision measurement applications. It shares the VQFN-32 footprint with other devices in the family but differs in channel count and specific performance parameters. The IRHBR designation indicates the tape-and-reel packaging variant suitable for automated assembly processes.

Replacement Considerations

Direct pin-compatible replacements within the same series may offer different channel counts or sampling rates. Verify electrical compatibility before substitution. No alternative part numbers are confirmed in the provided source material.
