Shenzhen Mingjiada Electronics Co., Ltd. a professional recycling service provider with nearly three decades of experience in the electronic components industry, consistently offers competitive cash prices for Texas Instruments (TI) INA790AEVM evaluation modules.
Overview
The INA790AEVM evaluation module enables users to evaluate the INA790x current sense amplifier. This device is a bidirectional, ultra-precision current sense amplifier utilizing 75A EZShunt™ technology with a voltage range of -4V to 110V. The TI INA79xEVM provides a platform supporting gain and reference voltage configuration.
Acquisition Product Core Parameters
1. Evaluation Module Features
Integrated EZShunt™ technology: On-board INA790A chip with integrated 400µΩ Kelvin-connected shunt resistor, supporting ±75A continuous current (25°C) and ±50A (125°C)
Ultra-wide common-mode range: -4V to 110V common-mode voltage, independent of supply voltage, supporting high-side and low-side current sensing
Ultra-High Accuracy: System gain error ±0.35%, 160dB DC CMRR, 114dB AC CMRR (50kHz), offset current only ±30mA
Enhanced PWM Rejection: Supports switching frequencies up to 125kHz, effectively suppressing dv/dt common-mode transient interference, ideal for real-time current measurement in motor drives
Adjustable Gain: Gain adjustable from 20mV/A to 400mV/A via external resistor divider network
Temperature alert: ALERT pin triggers and illuminates onboard LED D2 when integrated shunt resistor reaches 160°C
High-current wiring: Large copper planes and screw-type load connectors (IS+/IS-) support heavy-gauge wire connections
2. Electrical and Packaging Parameters
Operating voltage: 2.7V to 5.5V single supply, maximum supply current 4.25mA
Operating Temperature: -40°C to +125°C extended industrial temperature range
Package: 15-pin VQFN package; evaluation board provides full test point access
Evaluation Board Configuration: Single PCB design supports evaluation of four devices (INA790A/790B/791A/791B), differing only in U1 device
Evaluation Module Applications
Motor drivers, solenoids, and actuators
Injection molding machines, cordless power tools
