Shenzhen Mingjiada Electronics Co., Ltd. specializes in the electronic component supply and demand sector. We now simultaneously offer bulk supply and inventory buyback services for the Texas Instruments ALM2402Q1EVM dual high-current amplifier evaluation module. This initiative provides ample stock support for R&D and manufacturing enterprises while establishing an efficient monetization channel for holders of idle inventory, enabling precise resource circulation and maximizing value.
Product Overview
The ALM2402Q1EVM is an official evaluation module from Texas Instruments (TI), specifically designed to evaluate the ALM2402-Q1 automotive-grade dual high-current operational amplifier. Configured by default as a unity-gain amplifier and optimized for the orderable ALM2402QDRRRQ1 variant, this module delivers a flexible, high-performance testing and solution validation platform for automotive electronics, industrial control, and sensing system developers.
Core Features and Functions
1. Flexible Configuration Architecture
The evaluation board features numerous slots for unpopulated resistors, allowing customers to freely add filters, custom feedback components, and load circuits as needed. Each non-soldered component location provides multiple-size package pads, maximizing testing flexibility and enabling rapid assembly of various topologies such as inverting, non-inverting, and buffer configurations.
2. Comprehensive Test Interfaces
Input: Equipped with SMA connectors and test points supporting differential or single-ended signal input
Output: Large screw terminals (J3) facilitate connection to heavy-duty test equipment, enabling high-current output testing
Power: Separate input-stage power (VCC) and output-stage power (VCC_1/VCC_2) with voltage range 4.5V to 16V, supporting split-power configurations
3. Comprehensive Protection Mechanisms
Over-Temperature Flag (OTF): Integrated Zener diode configuration supports bidirectional OTF indication, triggering when junction temperature exceeds 157-175°C thresholds
Output Current Limiting: Built-in short-circuit current protection prevents overload damage
Reverse Polarity Protection: Jumper J5 provides VCC_S reverse polarity protection for enhanced system safety
4. Automotive-Grade Certification
Complies with AEC-Q100 Grade 1 standards, operating within -40°C to +125°C ambient temperatures. Suitable for demanding automotive environments like engine compartments.
