ADS1204IRHBR

Overview

The ADS1204IRHBR is a four-channel, 16-bit sigma-delta analog-to-digital converter (ADC) manufactured by Texas Instruments. It integrates a programmable gain amplifier and an internal oscillator to support high-precision data acquisition. The device operates on a single supply voltage ranging from 2.7V to 5.5V for both analog and digital domains. It delivers a parallel digital interface with a maximum sampling rate of 40k samples per second. The component is housed in a 32-pin VQFN package measuring 5x5 mm, designed for surface-mount installation. It supports differential or pseudo-differential input configurations.

Feature Summary

• Four-channel 16-bit resolution with integrated programmable gain amplifier
• Parallel digital output interface supporting up to 40kSPS data rate
• Single-supply operation from 2.7V to 5.5V for analog and digital sections
• Integrated internal oscillator eliminates need for external clock sources

Applications

• Industrial process control systems requiring multi-channel signal conditioning
• Portable battery-powered instrumentation due to low power consumption
• Medical equipment such as ECG monitors and portable diagnostic devices
• Weight scales and force measurement platforms

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pinout compatibility and electrical specifications. Ensure the procurement channel provides original manufacturer documentation to validate RoHS compliance and moisture sensitivity level ratings before integration into production designs.

Selection Notes

Select this component when four simultaneous channels with 16-bit precision are required at moderate speeds. The internal oscillator simplifies board layout compared to external clock solutions. Verify that the host microcontroller supports the parallel interface timing requirements and that the 2.7V to 5.5V supply range matches the system power architecture.

Part Context

This part belongs to the ADS1204 family of precision ADCs. The IRHBR suffix indicates a tape-and-reel packaging format suitable for automated surface-mount assembly processes. It serves as a specialized data acquisition solution within Texas Instruments' broader portfolio of mixed-signal converters.

Replacement Considerations

Consult the official datasheet for direct pin-compatible alternatives within the same family. Verify that any substitute maintains the 16-bit resolution, 40kSPS speed, and parallel interface compatibility.
