Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps

1. Overview

Linear amplifiers are analog ICs that process continuous signals with high fidelity. This category includes instrumentation amplifiers (In-Amps), operational amplifiers (OP Amps), and buffer amplifiers. They are critical in signal conditioning, filtering, and voltage amplification across electronics, medical devices, and industrial systems.

2. Main Types and Functional Classification

Type	Functional Characteristics	Application Examples
Instrumentation Amplifiers	High CMRR, low offset voltage, fixed/gain-programmable	Sensor bridges, medical instrumentation, precision data acquisition
Operational Amplifiers	Voltage feedback, high gain, configurable circuits	Active filters, integrators, comparators, audio amplifiers
Buffer Amplifiers	High input impedance, unity gain, drive capability	ADC drivers, signal isolation, impedance matching

3. Structure and Composition

Typical IC construction includes: - Differential Input Stage: Bipolar/JFET transistors for high impedance - Gain Stage: Cascoded amplification with laser-trimmed resistors - Output Stage: Class AB push-pull for low distortion - Protection Circuits: ESD protection, thermal shutdown Packaged in 8-20 pin configurations (SOIC, TSSOP, QFN).

4. Key Technical Specifications

Parameter	Importance
Gain Bandwidth Product (GBP)	Determines frequency response capability
Input Offset Voltage (Vos)	Impacts DC precision in low-level signal amplification
Slew Rate (SR)	Defines maximum signal transition speed
