OPA602AP

OPA602AP Description

The OPA602AP from Texas Instruments is a high-performance, general-purpose operational amplifier (op-amp) from the Difet® series, designed for precision analog applications. This obsolete but robust IC features a 6.5 MHz gain bandwidth product, 35V/µs slew rate, and ultra-low 2 pA input bias current, making it suitable for high-speed, low-noise signal conditioning. With a 10 V to 36 V supply voltage range and 3 mA supply current, it balances power efficiency with dynamic performance. The OPA602AP is housed in an 8-pin DIP (Through Hole) package, ensuring compatibility with legacy systems. Its ROHS3 compliance and REACH unaffected status highlight its adherence to environmental standards.

OPA602AP Features

• Ultra-Low Input Bias Current (2 pA): Ideal for high-impedance sensor interfaces and precision integrators.
• High Slew Rate (35V/µs): Enables fast signal response in data acquisition and pulse amplification.
• Wide Supply Range (10 V to 36 V): Supports flexible power configurations in industrial and test equipment.
• Difet® Technology: Provides low noise, high accuracy, and minimal drift over temperature.
• 20 mA Output Current: Capable of driving moderate loads directly.
• 1 mV Input Offset Voltage: Ensures precision in DC-coupled applications.

OPA602AP Applications

The OPA602AP excels in demanding analog circuits where speed, precision, and stability are critical:

• Medical Instrumentation: ECG amplifiers, photodiode preamps due to low noise and high CMRR.
• Test & Measurement: High-speed data converters, oscilloscope front-ends leveraging its slew rate.
• Industrial Control: PID controllers, strain gauge amplifiers benefiting from low drift.
• Audio Systems: Active filters and high-fidelity preamplifiers with low distortion.
• Legacy System Upgrades: Drop-in replacement for older Difet® op-amps in military/aerospace systems.

Conclusion of OPA602AP

While marked obsolete, the OPA602AP remains a reliable choice for precision analog designs requiring high speed, low noise, and wide voltage range. Its Difet® architecture and versatile performance make it a standout for specialized applications, though designers should consider modern alternatives for new projects. Texas Instruments' legacy support ensures continued availability for critical systems.
