ADOP37GH/+

Overview

The ADOP37GH/+ is a low-noise, precision, high-speed operational amplifier from Analog Devices Inc. It features a gain-bandwidth product of 63 MHz and a slew rate of 17 V/µs. The device offers an input offset voltage as low as 25 µV with a maximum drift of 0.6 µV/°C. Input bias current is typically 10 nA, and the open-loop gain reaches 1.8 million. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• Optimized for high-gain applications exceeding five times amplification
• Utilizes on-chip zener-zap trimming for stable offset performance
• Incorporates bias-current cancellation circuitry for low input currents

Applications

• Microphone preamplifiers
• Tape head preamplifiers
• Phono preamplifiers
• High-speed signal conditioning for data acquisition systems

Procurement Notes

Verify the specific suffix requirements for military-grade specifications when ordering. Confirm package availability and lead times directly with authorized distributors or the manufacturer. Ensure compatibility with existing board layouts by checking pin configurations against the official datasheet before procurement.

Selection Notes

Select this component for designs requiring high speed combined with precision in gains greater than five. It serves as a direct replacement for OP-07, SE5534, and OP-27 in high-performance applications. Consider the operating temperature range and packaging options suitable for the intended environment.

Part Context

The OP37 series bridges the gap between low-speed precision amplifiers and high-speed general-purpose devices. It maintains the low offset and drift characteristics of the OP07 while significantly improving slew rate and bandwidth. This makes it suitable for instrumentation where both accuracy and speed are critical.

Replacement Considerations

Public confirmed substitute part numbers include OP-07, SE5534, and OP-27.
