TIINA240EVM
Overview
The INA240EVM is an evaluation module designed to test the INA240 precision current-sense amplifier, which is optimized for high-side or low-side current sensing in PWM systems. It supports a wide common-mode input range from -4V to 80V and utilizes a zero-drift architecture to maintain high accuracy across its operating temperature range. The board allows for easy verification of the device's enhanced PWM rejection, making it ideal for motor and solenoid applications.
Why Choose This Part
The module features enhanced PWM rejection that suppresses large transients and reduces signal noise without requiring heavy external filtering. It offers a low maximum error of 0.2 percent and zero-drift performance across a temperature range of -40C to 125C, ensuring stable measurements in harsh environments.
Applications
Key Specifications
Getting Started
To begin evaluation, connect a 2.7V to 5.5V supply to the V+ header and apply a differential voltage across the shunt resistor inputs. The board is designed for easy probing of the single-ended output with an oscilloscope or ADC to verify the 400kHz bandwidth and 2V/us slew rate.
