Texas Instruments INA290EVM

Overview

INA290EVM from Texas Instruments is an evaluation module designed to characterize the INA290 voltage-output, high-side current shunt monitor across five discrete gain options (20 V/V to 500 V/V), supporting common-mode voltages up to +110 V and supply voltages from 2.7 V to 20 V. It enables engineers to validate current sensing accuracy in power supply monitoring, motor control feedback, and battery management systems using solderable 2512 shunt resistors and configurable input/output filtering.

For engineers reviewing the INA290EVM datasheet, INA290EVM pinout, INA290EVM application, or INA290EVM equivalent, this EVM provides direct hardware access to all five INA290 variants (A1–A5) on a single PCB, test points for Vin+, Vin–, Vout, and VS, and user-configurable pads for input/output filtering - critical for validating high-voltage unidirectional current sensing under real system conditions.

Technical Context

The INA290EVM implements five independent evaluation panels-each populated with one specific INA290 variant (A1–A5)-on a single PCB, allowing side-by-side comparison of gain-dependent output response. Each panel includes dedicated test points, unpopulated 2512 shunt pads (R1_An), and 0-Ω jumper pads (R2/R3/R4_An) for optional RC filtering at IN+, IN–, and OUT.

It supports both floating differential input emulation and direct series connection to external shunts, with safe current measurement up to 5 A. The board uses SC-70-5 packaged INA290 devices and incorporates 0.1-µF ceramic bypass capacitors (C1_An) per channel, aligned with TI's recommended layout for high-common-mode-voltage current sensing.

FAQ

What is the primary function of the INA290EVM?

The INA290EVM is a Texas Instruments evaluation module used to experimentally verify the performance of the INA290 high-side current shunt monitor across its five gain options (20–500 V/V). It allows engineers to measure output voltage response under controlled differential input and high common-mode voltage conditions without designing custom circuitry. The INA290EVM includes test points, shunt resistor pads, and filter configuration options to accelerate validation of current sensing in real-world power systems.

Does the INA290EVM include the actual INA290 ICs?

Yes, the INA290EVM includes five pre-soldered INA290 devices-one of each gain variant (A1 through A5)-mounted on separate evaluation panels. Each device is housed in the SC-70-5 package (DCK0005A) and labeled as U1_A1 through U1_A5 in the bill of materials. These are production-grade ICs, not placeholders or dummy components, enabling immediate functional testing upon power-up.

Can the INA290EVM be used with external shunt resistors?

Yes, the INA290EVM provides unpopulated 2512-footprint pads (R1_An) on each panel to solder external shunt resistors directly between Vin+ and Vin– inputs. The board supports shunts rated for up to 3 W and 5 A continuous current. Engineers must ensure external shunt power dissipation, thermal derating, and mechanical mounting comply with safety guidelines before energizing the circuit.

What safety precautions apply when using the INA290EVM?

The INA290EVM is classified as a Texas Instruments High Voltage Evaluation Module (HV EVM) and requires strict adherence to TI's HV EVM safety guidelines: de-energize before probing, use insulated tools, maintain barriers around energized areas, limit input current to ≤5 A, and avoid touching live circuits. It is intended only for qualified professionals in lab environments-not for production or field deployment.

Is the INA290EVM compatible with other current sense amplifier families?

No, the INA290EVM is purpose-built for the INA290 family (A1–A5 variants) and is not mechanically or electrically compatible with other current sense amplifiers. Its test point locations, pad layouts, and internal routing match only the SC-70-5 pinout and gain-specific configurations of the INA290. Substituting other ICs would require redesigning the PCB layout and revalidating signal integrity and common-mode rejection.
