OP490GSZ-REEL

Instrumentation, Op Amps, Buffer Amps Overview

The OP490GSZ-REEL is a micropower quad operational amplifier manufactured by Analog Devices Inc. It operates from single supplies of 1.6 V to 36 V or dual supplies of ±0.8 V to ±18 V. The device features a maximum input offset voltage of 1.0 mV and a typical large signal voltage gain of 800 V/mV. Supply current is limited to 80 μA maximum, while each amplifier delivers over 5 mA output current. Key dynamic parameters include a 20 kHz gain-bandwidth product and a 12 V/ms slew rate. It is housed in a 16-lead SOIC package.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Supports single-supply operation with input and output voltage ranges including ground for zero-in, zero-out functionality.
• Provides high output drive capability delivering over 5 mA per amplifier channel.
• Features low supply current consumption suitable for battery-powered applications.
• Includes internal protection resistors allowing inputs to withstand voltages 20 V beyond either supply rail.

Instrumentation, Op Amps, Buffer Amps Applications

• Battery-powered portable instruments
• Remote sensors
• Micropower voltage-controlled oscillators
• Single-supply programmable gain amplifiers

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific REEL suffix indicates tape-and-reel packaging rather than tube packaging when sourcing components. Confirm RoHS compliance status via the manufacturer's ordering guide as indicated by the Z suffix designation. Ensure the 16-lead SOIC package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring low quiescent current alongside high output drive capabilities. The wide single-supply range accommodates various battery chemistries. Verify that the 20 kHz bandwidth meets signal processing needs. Consider the 1.0 mV maximum offset voltage for precision requirements. Ensure thermal management aligns with the specified operating temperature range.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the OP490 series of micropower quad operational amplifiers. It shares functional characteristics with other variants like the OP490GSZ but differs in packaging format. The series is designed for space-constrained applications requiring multiple amplifier channels within a single integrated circuit package.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

OP490GSZ serves as the tube-packaged equivalent. OP490GP offers a 14-lead PDIP alternative. Cross-reference pinouts carefully between SOIC and DIP packages to ensure compatibility during substitution.
