Shenzhen Mingjiada Electronics Co., Ltd. — Long-term supplier of a diverse range of ADI amplifier chips, including but not limited to: operational amplifiers, differential amplifiers, audio amplifiers, and multiple other product categories. Mingjiada Electronics maintains robust and reliable supply channels, exercising strict control over the supply chain to ensure the stability and reliability of supplied products. Inventory covers the full range of ADI amplifier chips, supporting one-stop procurement.

I. ADI Operational Amplifiers (Op-Amps) — Core Components of Analogue Circuits
Models supplied by Mingjiada include, but are not limited to:
OP297GSZ: Dual-channel, precision, low-power operational amplifier. Utilising a space-saving, industry-standard 8-pin SO package, it integrates precision performance with low-power characteristics.
ADA4000-2ARMZ: J-FET dual-channel linear operational amplifier. Features high input impedance (input bias current only 5pA) and a wide supply voltage range (±4V to ±18V or single supply 8V to 36V).
OP270GP: Dual-channel, ultra-low-noise precision operational amplifier, commonly used in audio applications. Its gain-bandwidth product is 12MHz, with a slew rate of 5 V/µs.
AD8566ARMZ: 16V dual rail-to-rail operational amplifier. Operates from a single supply (4.5 V to 16 V), with inputs capable of exceeding supply rails and outputs providing rail-to-rail swing.

II. ADI Differential Amplifiers – Amplify the difference between two input signals while suppressing common-mode signals
Mingjiada supplies models including, but not limited to:
AD8139ARDZ: Ultra-low-noise, high-performance fully differential amplifier providing rail-to-rail output. Features include low noise (2.25 nV/√Hz voltage noise, 2.1 pA/√Hz current noise), high spurious-free dynamic range (SFDR) (e.g., 98 dBc at 1 MHz), and wide bandwidth (3 dB bandwidth 410 MHz, G=1), with slew rates up to 800 V/µs.
AD8274ARZ-R7: An ultra-low distortion, precision differential amplifier. It exhibits exceptionally high slew rate (9800 V/µs) and a wide -3dB bandwidth (2.9GHz). It operates from a single supply voltage of 3 V to 3.6 V, drawing 40mA of supply current.

III. ADI Audio Amplifiers — For driving loudspeakers or headphones, amplifying audio signal power
Mingjiada Electronics supplies Class D audio power amplifiers such as the TPA3116D2, achieving efficiency exceeding 90%, and also offers Class AB audio power amplifiers including the LM3886, TDA2030/TDA2050.
Additionally, Mingjiada Electronics supplies ADI Automotive Audio Bus (A2B®) products, including chips such as the AD2428W series master/slave transceivers. These enable the construction of high-performance, low-latency in-vehicle audio networks supporting multi-channel audio transmission, Active Noise Cancellation (ANC), and voice interaction systems.

IV. ADI Instrumentation Amplifiers and Other Specialised Amplifiers
Beyond the aforementioned categories, Mingjiada Electronics also supplies other high-performance specialised amplifiers.
Instrumentation Amplifiers: Examples include the AD620, a classic high-precision instrumentation amplifier featuring extremely high input impedance, exceptional common-mode rejection ratio (CMRR), excellent gain accuracy, and low offset drift. It is ideally suited for sensor signal conditioning and precision measurement applications.
Variable Gain Amplifiers, Logarithmic Amplifiers/Detectors, Isolation Amplifiers, etc.: Mingjiada Electronics' supply portfolio also encompasses these specialised amplifier types to address more diverse system requirements.
