AD8632ARM-R2

Overview

The AD8632ARM-R2 is a dual, low-power operational amplifier from Analog Devices Inc., housed in an 8-lead µSOIC package. It operates on a single supply voltage ranging from 1.8 V to 6 V with a typical supply current of 300 µA per amplifier at 5 V. The device features rail-to-rail input and output capabilities, a gain-bandwidth product of 5 MHz at 5 V, and a slew rate of 3 V/µs. It maintains an extended industrial operating temperature range from -40°C to +125°C.

Feature Summary

• Rail-to-rail input and output swing capability across the full supply voltage range
• Low power consumption suitable for battery-operated applications
• High bandwidth and fast slew rate for signal processing tasks
• Extended industrial temperature rating for harsh environments

Applications

• Portable communications equipment
• Sensor interface circuits
• Active filters
• ASIC input drivers
• Battery-powered devices

Procurement Notes

Verify that the ordering suffix matches the required tape-and-reel quantity and packaging variant. Confirm the component date code aligns with project requirements. Ensure ESD handling protocols are strictly followed during assembly due to the sensitivity of the CMOS bipolar process. Cross-reference the manufacturer's latest datasheet revision to confirm pinout and electrical specifications remain unchanged.

Selection Notes

Select this component when a dual-channel solution is required within space-constrained designs. It is appropriate for applications needing rail-to-rail performance at low supply voltages. Consider the thermal resistance characteristics of the µSOIC package for heat dissipation. Evaluate the noise density and offset voltage against specific signal integrity requirements.

Part Context

This part belongs to the AD8631/AD8632 family of precision, low-power operational amplifiers. While the AD8631 is a single-channel device, the AD8632 provides two identical channels in one package. Both share the same XFCB process technology, ensuring consistent dynamic performance and low noise characteristics across the family.

Replacement Considerations

The AD8632AR (SOIC-8) offers identical electrical specifications but utilizes a standard SOIC package instead of the narrower µSOIC form factor. Designers must verify footprint compatibility before substituting between these package options.
