In the rapidly evolving field of electronic R&D, numerous evaluation boards used for project validation—particularly core signal chain components like operational amplifier evaluation modules—often become idle after fulfilling their purpose, leading to asset stagnation and storage cost pressures. Addressing this industry pain point, Shenzhen Mingjiada Electronics Co., Ltd., leveraging over two decades of specialized expertise, has launched a dedicated cash acquisition service globally. This initiative aims to efficiently manage idle Texas Instruments (TI) single-channel, dual-channel, and quad-channel operational amplifier evaluation modules (EVMs) for enterprises, R&D institutions, and engineers worldwide. It empowers clients to rapidly liquidate inventory assets and recover capital.
Core Acquisition Scope
1. Single-Channel Operational Amplifier Evaluation Modules: Designed for standalone signal conditioning channels, suitable for precision sensor interfaces, optoelectronic detection, medical monitoring equipment, and similar applications. Representative models include OPA659EVM (650MHz high-speed JFET input) and OPA858QDSGRQ1 (5.5GHz automotive-grade ultra-wideband amplifier), supporting single- or dual-supply configurations with optimized 50Ω test interfaces.
2. Dual Operational Amplifier Evaluation Modules: Covering mainstream applications including differential signal chains, instrumentation amplification, and audio processing, these modules are the preferred choice for validation in industrial automation and communication infrastructure. Acquired models include the OPA2836IDGSEVM (205MHz voltage feedback type), LMH6521EVAL/NOPB (1.2GHz variable gain dual-channel), THS4131EVM, and DEM-OPA-RUN-EVM high-speed evaluation boards. These modules typically utilize compact packages like MSOP and VQFN, supporting flexible inverting/non-inverting configurations.
3. Quad Operational Amplifier Evaluation Modules: Designed for multi-channel data acquisition systems, multi-axis motor drives, and complex signal routing applications. While search results do not explicitly list specific quad models, Mingjiada's extensive portfolio and recycling capabilities in TI amplifier evaluation boards ensure coverage of all quad op-amp evaluation boards, meeting diverse inventory management needs.
