Below is a classification of the amplifier products supplied by Mingjiada Electronics and their corresponding models:
1. Operational Amplifiers
Common subcategories:
General-purpose: such as LM358, LM324, TL072, TL082, NE5532.
Precision/low offset/low drift: with extremely low input offset voltage and temperature drift, suitable for high-precision measurements (sensor signal conditioning, instruments and meters).
Such as AD620 (instrumentation amplifier), AD8628, OPA277, OPA2188, LT1013, MCP6V01.
High-speed type: High gain-bandwidth product and slew rate, suitable for video, communication, and high-speed data acquisition.
Such as AD8009, AD811, OPA847, THS3091, LMH6629.
Low-noise type: Extremely low input voltage noise and current noise, suitable for preamplification (microphones, sensors, medical devices).
Examples include AD797, OPA1612, OPA627, LT1028, ADA4898.
Low-power/ultra-low-power type: Extremely low quiescent current, suitable for battery-powered devices and portable equipment.
Examples include MCP6001/2/4, TLV2462, LPV821, MAX44260, ADA4505.
High-voltage type: Wide operating voltage range (far exceeding ±15V), suitable for industrial control, test equipment, and power management.
Examples: OPA454, OPA548, LT1210, ADA4700.
Rail-to-rail input/output type: Input and/or output signal ranges are very close to the power supply rails (V+ and V-), suitable for low-voltage single-supply systems.
Such as MCP6001/2/4, TLV2462, AD8605/AD8615/AD8625, OPA365, LTC6258.
Current feedback type: Features extremely high slew rate and bandwidth, almost independent of gain, commonly used in high-speed video and communication applications.
Examples include AD8009, AD811, THS3091, and OPA695.
2. Power Amplifiers
Common subcategories:
Audio Power Amplifiers:
Class AB: Traditional type, good sound quality, moderate efficiency.
Examples include LM3886, TDA2030/TDA2050, and TPA3116D2.
Class D: High efficiency (switching mode), compact size with low heat generation, dominant in portable and high-efficiency applications.
Examples: TPA3116D2, TAS5611A, MAX98357, IRS2092S (requires external MOSFET).
RF Power Amplifiers: Operate at high frequencies (RF) for wireless communication transmitter links.
3. Instrumentation amplifiers
Description: A high-performance operational amplifier with a special structure, featuring extremely high input impedance, extremely high common-mode rejection ratio (CMRR), excellent gain accuracy, and low offset drift.
Representative models: AD620, AD623, AD8221, INA128, INA333, LT1167, MCP6N11.
4. Differential Amplifiers
Description: Amplifies the difference between two input signals. The structure is simpler than that of instrumentation amplifiers, with performance metrics (such as CMRR) typically lower than those of instrumentation amplifiers, and lower cost. Can be used for level conversion, single-ended to differential conversion, etc.
Representative models: INA133, INA143, AD8276, LT1990, THS4521
Quality Assurance: Mingjiada Electronics has a stable and reliable supply chain, strictly controlling the supply chain to ensure the stability and reliability of supplied products.
Adequate Inventory Supply: Mingjiada Electronics maintains sufficient amplifier chip inventory to meet customer needs for small-batch samples and large-volume purchases.
Fast Delivery: Mingjiada Electronics relies on an efficient logistics system to ensure products are delivered to customers quickly.
