OP497GS

OP497GS Description

The OP497GS from Analog Devices Inc. is a high-precision, quad-channel general-purpose operational amplifier (op-amp) housed in a 16-SOIC surface-mount package. Designed for demanding analog applications, it operates over a 4V to 40V supply range, making it versatile for both low and high-voltage systems. With an ultra-low input bias current of 60 pA and a minimal input offset voltage of 80 µV, the OP497GS ensures high accuracy in signal conditioning and amplification tasks. Its 525µA per channel supply current and 500 kHz gain bandwidth product strike a balance between power efficiency and performance, while the 0.15V/µs slew rate ensures stable transient response.

OP497GS Features

• Quad-Channel Design: Integrates four independent op-amps in a single package, saving board space.
• Wide Supply Range (4V–40V): Suitable for diverse power environments, from battery-powered devices to industrial systems.
• Low Power Consumption: 525µA per channel minimizes energy usage in portable and embedded applications.
• High Precision: 80 µV offset voltage and 60 pA bias current enhance measurement accuracy.
• Robust Output Drive: 25 mA output current per channel supports moderate load requirements.
• Surface-Mount Package (16-SOIC): Facilitates compact PCB designs and automated assembly.

OP497GS Applications

The OP497GS excels in precision analog circuits, including:

• Sensor Signal Conditioning: Ideal for amplifying low-level signals from thermocouples, strain gauges, or pressure sensors.
• Active Filters: Its stable bandwidth and low noise suit Butterworth or Chebyshev filter designs.
• Industrial Control Systems: Reliable performance in PLCs, motor controllers, and instrumentation amplifiers.
• Battery-Powered Devices: Low quiescent current extends battery life in portable medical or IoT devices.
• Voltage Followers/Buffers: Maintains signal integrity in high-impedance circuits.

Conclusion of OP497GS

The OP497GS combines precision, low power, and multi-channel integration, making it a standout choice for engineers designing compact, high-accuracy analog systems. While marked obsolete, its legacy performance in industrial, medical, and portable applications remains noteworthy.
