OP37-001C

Instrumentation, Op Amps, Buffer Amps Overview

The OP37-001C is a die form of the Analog Devices OP37 low-noise, precision, high-speed operational amplifier. It features a maximum supply span of 22 V and a slew rate of 17 V/µs. The device offers a gain-bandwidth product of 63 MHz and an open-loop gain of 1.8 million. Input offset voltage is guaranteed at 10 µV with a drift of 0.2 µV/°C. Noise performance includes 80 nV p-p (0.1 Hz to 10 Hz) and 3 nV/√Hz at 1 kHz. Common-mode rejection ratio reaches 126 dB.

• Incorporates bias-current cancellation circuitry for low input bias current
• Provides instrumentation-grade noise and drift characteristics

Instrumentation, Op Amps, Buffer Amps Applications

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

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify that the procurement source explicitly identifies the item as a bare die or die-on-film frame configuration rather than a packaged component. Confirm the manufacturer designation matches Analog Devices Inc. Ensure the part number suffix corresponds to the specific die variant required for custom packaging integration.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when designing circuits with gains greater than five, where the OP37's optimized architecture provides superior speed compared to the OP27. It serves as a direct replacement for the 725, OP-07, and SE5534 in high-gain configurations. Suitable for applications requiring low noise and high open-loop gain.

Instrumentation, Op Amps, Buffer Amps Part Context

The OP37-001C represents the unencapsulated die version of the OP37 operational amplifier family. This format allows system integrators to incorporate the amplifier into custom hybrid modules or specialized packaging solutions while retaining the original device's electrical specifications and performance characteristics.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Publicly confirmed substitute part numbers include OP-07, 725, and SE5534 for applications with gains greater than five.
