Overview
The ADS1235IRHBR is a precision analog-to-digital converter manufactured by Texas Instruments, housed in a 32-VQFN package. It features a 24-bit resolution and supports up to 7.2 kSPS sampling rate with three differential or single-ended channels. The device utilizes a sigma-delta architecture and operates on a 5 V analog supply and a 2.7 V to 5.25 V digital supply. It includes an internal reference, gain error of 0.05%, and interfaces via SPI. Operating temperatures range from -40°C to +125°C.
Feature Summary
- Integrates a programmable gain amplifier and signal conditioning circuitry for direct sensor interfacing
- Provides high-precision data conversion with integrated internal voltage reference
- Supports flexible input configurations through selectable differential or single-ended channel modes
Applications
- Industrial process control systems requiring multi-channel precision measurement
- Weigh scales and load cell instrumentation
- Medical equipment utilizing strain gauge sensors
Procurement Notes
Verify the specific suffix against official documentation to confirm temperature grade and packaging type. Ensure compatibility with system power supplies and SPI timing requirements before integration. Cross-reference the manufacturer datasheet for mechanical dimensions and thermal characteristics.
Selection Notes
Select this component when high-resolution multi-channel acquisition is required without external amplification. Compare performance metrics such as noise density and linearity against other delta-sigma ADCs. Confirm that the 32-VQFN package fits the available PCB real estate and thermal management strategy.
Part Context
This part belongs to the ADS1235 family of precision ADCs designed for low-noise applications. It shares architectural similarities with other devices in the series but offers specific channel counts and interface options tailored for industrial sensing tasks.
Replacement Considerations
ADS1235IRHBT is a verified alternative within the same product family offering identical electrical specifications.
