company blog about [Genuine Product] Supply Texas Instruments INA851EVM Low-Noise High-Speed Fully Differential Instrumentation Amplifier Evaluation Module

INA851EVM Evaluation Module Product Overview

The INA851EVM is a specialized evaluation module from Texas Instruments designed for the INA851 low-noise, high-speed, fully differential instrumentation amplifier. It serves as a high-performance development platform within TI's Precision Signal Chain product family. This evaluation board features a standard 2.00-inch × 2.00-inch (50.8mm × 50.8mm) PCB design with an optimized layout to minimize parasitic capacitance and noise. It serves as an ideal tool for verifying fully differential signal conditioning performance, prototyping designs, and performing system debugging.

1. Evaluation Core: INA851 Fully Differential Instrumentation Amplifier

The core of this evaluation module is TI's INA851 chip, designed for seamless integration between sensors and fully differential input ADCs. It offers the following key features:

Exceptional DC Accuracy: Utilizing TI's advanced ultra-β input transistor technology, it achieves ultra-low input offset voltage, offset drift, and input bias current, ensuring long-term stability and accuracy in precision measurements.

Outstanding Noise Performance: Features extremely low input voltage noise and current noise, effectively preserving signal-to-noise ratio at the front end. This makes it ideal for amplifying minute signals, such as sensor outputs.

Wide dynamic range: Gain can be linearly set over an extremely wide range from 0.2 V/V to 10,000 V/V using a single external resistor, providing unmatched flexibility to accommodate various input signal amplitudes.

Fully differential output: Optimized for direct driving of fully differential input ADCs, effectively suppressing common-mode noise and enhancing system immunity to interference.

2. Thoughtfully Designed Evaluation Board Features

The EVM board itself is designed with engineer evaluation and debugging convenience in mind:

Convenient Test Interfaces: On-board SMA connectors and multiple test points allow users to quickly connect test equipment for signal measurement and analysis at critical nodes.

Flexible Configuration: Provides easily accessible VOCM (output common-mode voltage), VCLAMP+, and VCLAMP- (output clamping) pins for convenient output common-mode level setting and protection of downstream ADCs from voltage overshoot damage.

Default and Adjustable Gain: The module defaults to 1 V/V gain while reserving gain resistor positions, enabling users to easily modify configurations to evaluate device performance at different gains.

Application Scenarios

The INA851EVM evaluation module and the INA851 amplifier solution it represents are widely used in applications demanding stringent signal quality:

Precision Test and Measurement: High-performance benchtop instruments, data acquisition systems.

Medical and Healthcare Equipment: Bioelectric signal amplification in electrocardiograms (ECG), electroencephalograms (EEG), and blood analyzers.

Industrial Sensing and Control: Bridge amplification for pressure sensors, current/voltage detection in industrial process control.

Communications and Audio Systems: Applications requiring high-quality differential signal conditioning.
