Mingjiada Supply TI INA187EVM Evaluation Module, For Evaluating The INA187 Current Sense Amplifier

Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of Texas Instruments (TI) INA187EVM evaluation modules. This is a flexible platform specifically designed to evaluate all gain variants of the INA187 bidirectional high-precision current sense amplifier.

The unique feature of the INA187EVM evaluation module lies in its integration of three identical, independent evaluation boards within a compact module. This enables engineers to conveniently test the INA187's 20V/V, 50V/V, and 100V/V gain variants simultaneously or individually, facilitating rapid selection of the optimal solution for specific applications.

INA187EVM Evaluation Core: INA187 High-Precision Amplifier
At the heart of the INA187EVM evaluation module lies Texas Instruments' INA187 chip. This voltage-output current sensing amplifier is specifically engineered for precision measurement applications.

The INA187EVM stands out for its combination of high precision and high bandwidth. It delivers a high signal bandwidth of 650kHz (at 20V/V gain) and a slew rate of 2.5V/µs, whilst offering a DC common-mode rejection ratio (CMRR) of up to 120dB and a maximum gain error of only ±0.25%.

This enables the INA187 to excel not only in precise DC current measurement but also in applications demanding rapid response, such as transient current detection and fast overcurrent protection circuits.

The INA187 supports a wide common-mode voltage range from -2V to +42V and withstands voltages from -12V to +48V, offering robust adaptability and reliability. Powered by a single supply ranging from 2.7V to 12V, it maintains a low quiescent current of just 650µA, balancing performance with low power consumption.

INA187EVM Features:
Evaluate all gain options via the provided device board
Easily connect device pins via test points
Optional filtering at input and output pins via pads and sockets

Multiple input signal options provided, including soldered shunt resistors (2512) and methods for safely measuring currents up to 10A

The INA187EVM's hardware design prioritises both convenience and comprehensiveness for engineer evaluation. The evaluation module employs an innovative three-in-one structure. The entire module comprises three fully independent sub-boards with identical schematics, each featuring reserved solder pads for the INA187 chip. Engineers can readily disassemble the module as required, soldering different gain variants of the INA187 chip (A1: 20V/V, A2: 50V/V, A3: 100V/V) onto separate boards to evaluate all gain options in parallel.

The three parallel circuits on the INA187EVM evaluation board function like three concurrent experimental tracks. Engineers can simultaneously validate chip performance across different amplification levels on these tracks, swiftly completing the critical steps from device selection to circuit verification.
