Below are the amplifier product categories and relevant models supplied by Mingjiada Electronics:

I. Power Amplifiers

Description: Primarily designed to deliver substantial output power (current and voltage) to loads such as loudspeakers, motors, or antennas. Efficiency is typically a key metric.

Common Subcategories:

Audio Power Amplifiers:

Class AB: Traditional type offering good sound quality with moderate efficiency.

Examples: LM3886, TDA2030/TDA2050, 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).

Radio Frequency Power Amplifiers: Operate at high frequencies (RF), used in wireless communication transmitter chains.

Examples include band-specific GaAs/GaN PA modules or ICs (part numbers typically correlate strongly with frequency band and power rating).

II. Operational Amplifiers

Description: The most versatile and widely applied amplifier type. Used for signal amplification, filtering, mathematical operations (addition, subtraction, integration, differentiation, etc.), buffering, comparison, and more.

Common Subcategories:

General-purpose: Balanced performance, low cost, suitable for general applications.

Examples: LM358, LM324, TL072, TL082, NE5532.

Precision/Low-offset/Low-drift: Minimal input offset voltage and temperature drift, suitable for high-precision measurement (sensor signal conditioning, instrumentation).

Examples: AD620 (instrumentation amplifier), AD8628, OPA277, OPA2188, LT1013, MCP6V01.

High-Speed Type: High gain-bandwidth product and slew rate, suitable for video, communications, and high-speed data acquisition.

Examples: AD8009, AD811, OPA847, THS3091, LMH6629.

Low-noise type: Extremely low input voltage noise and current noise, suitable for preamplification (microphones, sensors, medical equipment).

Examples: AD797, OPA1612, OPA627, LT1028, ADA4898.

Low-power/ultra-low-power type: Very low quiescent current, suitable for battery-powered devices and portable equipment.

Examples: 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 approach the power rails (V+ and V-) closely, suitable for low-voltage single-supply systems.

Examples: MCP6001/2/4, TLV2462, AD8605/AD8615/AD8625, OPA365, LTC6258.

Current feedback type: Exhibits extremely high slew rate and bandwidth, largely independent of gain, commonly employed in high-speed video and communication driving applications.

Examples include AD8009, AD811, THS3091, OPA695.

III. Instrumentation Amplifiers

Description: A specialised high-performance operational amplifier featuring exceptionally high input impedance, outstanding common-mode rejection ratio, excellent gain accuracy, and low offset drift. Specifically engineered for the precise amplification of weak differential signals—particularly in the presence of strong common-mode interference—such as those from sensor outputs (strain gauges, thermocouples, bridges).

Representative Models: AD620, AD623, AD8221, INA128, INA333, LT1167, MCP6N11.

IV. Comparators

Description: Typically outputs a digital logic level, comparing two input voltages and indicating which is higher.

Representative models: LM393 (dual), LM339 (quad), LM311, MAX902/MAX903, ADCMP600.

V. Differential Amplifiers

Description: Amplifies the difference between two input signals. Structure is simpler than instrumentation amplifiers, with performance metrics (e.g., CMRR) typically lower than instrumentation amplifiers, and lower cost. Can be used for level conversion, single-ended to differential conversion, etc.

Representative models: INA133, INA143, AD8276, LT1990, THS4521 (FDA - fully differential amplifier, commonly used in high-speed ADC drivers).
