ADS124S06IRHBT

Overview

The ADS124S06IRHBT is a 24-bit, low-noise delta-sigma analog-to-digital converter (ADC) from Texas Instruments. It integrates a programmable gain amplifier (PGA), a precision internal reference, and an on-chip oscillator. The device supports up to six differential or twelve single-ended inputs via its multiplexer. It operates with an analog supply voltage ranging from 2.7 V to 5.25 V and a digital supply voltage between 2.7 V and 3.6 V. The maximum sampling rate is 4 kSPS. It features a serial peripheral interface (SPI) for communication and is housed in a 32-pin VQFN package.

Feature Summary

• Integrates excitation current sources (iDACs) for direct sensor excitation
• Includes built-in temperature sensor and general-purpose input/output (GPIO)
• Provides hardware-configurable 50 Hz and 60 Hz rejection filters

Applications

• Industrial process control systems
• Weigh scales and load cell measurements
• RTD and thermocouple temperature monitoring

Procurement Notes

Verify the specific suffix IRHBT indicates the 32-VQFN package and industrial temperature range. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure static-sensitive handling protocols are followed during assembly due to the moisture sensitivity level associated with this component type.

Selection Notes

Select this component when high-resolution measurement of low-level signals is required. It is suitable for applications needing integrated signal conditioning and sensor excitation capabilities. Consider the power consumption specifications relative to system battery life requirements. Verify that the SPI interface timing meets the host microcontroller's performance constraints.

Part Context

This part belongs to the ADS124S family of low-power, high-precision ADCs. It shares architectural similarities with the ADS124S08 but offers fewer input channels. The series is designed for cost-effective solutions in industrial instrumentation where noise performance and channel count must be balanced.

Replacement Considerations

The ADS124S06IRHBR is a tape-and-reel alternative within the same product line. Verify pinout compatibility and electrical parameter equivalence before substitution.
