AD8632ARMZ-REEL

Overview

The AD8632ARMZ-REEL is a dual, low-power, rail-to-rail input and output operational amplifier from Analog Devices. It operates on a single supply voltage ranging from 1.8 V to 6 V. The device features a gain-bandwidth product of 4 MHz at 1.8 V and 5 MHz at 5 V, with a typical slew rate of 3 V/µs. It exhibits a maximum input offset voltage of 4 mV and a typical supply current of 300 µA per amplifier at 5 V. The component is housed in an 8-lead µSOIC package and is specified for operation across the extended industrial temperature range of –40°C to +125°C.

Feature Summary

• Rail-to-rail input and output capability allows full signal swing over the entire supply voltage range.
• Low power consumption suitable for battery-powered applications with minimal quiescent current draw.
• High bandwidth and fast slew rate optimized for driving ASIC inputs and active filter circuits.

Applications

• Portable communications equipment
• Sensor interface circuits
• Active filters
• ASIC input drivers

Procurement Notes

Verify that the ordering suffix matches the required package type and reel quantity specifications. Confirm the manufacturer source is authorized to ensure component authenticity and traceability. Check for any specific environmental compliance certifications required by the target application standards before finalizing the purchase order.

Selection Notes

Select this component when a dual-channel amplifier is required for space-constrained designs. It is appropriate for systems operating on low single-supply voltages where rail-to-rail performance is critical. Consider the thermal characteristics of the µSOIC package if high ambient temperatures are expected within the industrial range.

Part Context

This part belongs to the AD8631/AD8632 family of precision operational amplifiers. While the AD8631 is a single-channel device, the AD8632 provides two identical channels in one package. Both share the same electrical characteristics and process technology, differing only in channel count and pin configuration.

Replacement Considerations

Direct replacements include other dual-channel, rail-to-rail op amps with similar supply voltage ranges and bandwidth. Verify pin compatibility and electrical parameter equivalence before substitution.

FAQ

Does the AD8632 exhibit phase reversal when the input exceeds the supply rails?

No, the AD8632 does not exhibit phase reversal even if the input signal exceeds the supply voltage by more than 0.6 V.

What is the maximum input bias current for this device?

The maximum input bias current is 500 nA over the extended industrial temperature range.
