ADA4805-2TRMZ-EPR7

Overview

The ADA4805-2TRMZ-EPR7 is a dual-channel, low-power, high-speed voltage feedback operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output capability and operates within an extended temperature range of -55°C to +125°C. Key electrical specifications include a gain-bandwidth product of 105 MHz, a slew rate of 250 V/µs, and a maximum supply current of 570 µA for both channels combined. The device exhibits a typical input offset voltage of 13 µV and an input bias current of 550 nA, supporting an output current of 58 mA per channel.

Feature Summary

• Dual-channel architecture with rail-to-rail output swing
• High-speed performance with 105 MHz gain-bandwidth product
• Low power consumption suitable for battery-operated applications
• Extended industrial temperature range operation

Applications

• Portable instrumentation requiring low power and high speed
• Video signal processing circuits
• Active filtering in communication systems
• Data acquisition front-ends

Procurement Notes

Verify the complete part number including the suffix EPR7, which indicates specific tape-and-reel packaging and environmental compliance. Confirm availability status as restricted or limited supply may apply. Ensure the operating environment falls within the specified -55°C to +125°C range. Cross-reference the datasheet revision to ensure compatibility with design requirements. Validate that the 8-MSOP package dimensions match the PCB footprint.

Selection Notes

Select this component when dual-channel amplification is required with minimal power budget. The 105 MHz bandwidth supports moderate-frequency signal conditioning. Compare against single-channel variants if only one amplifier is needed. Consider the 570 µA total supply current for thermal management. Verify that the rail-to-rail output meets the load drive requirements without additional buffering stages.

Part Context

This device belongs to the ADA4805 family of low-power, high-speed operational amplifiers from Analog Devices. The family includes single-channel (ADA4805-1) and dual-channel (ADA4805-2) versions. The TRMZ suffix denotes the MSOP package, while EPR7 specifies the reel packaging configuration. These amplifiers are designed for applications balancing speed and power efficiency.

Replacement Considerations

Direct substitutes include other dual-channel rail-to-rail op-amps with similar 105 MHz bandwidth and low quiescent current. Check pinout compatibility for the 8-MSOP package. Verify that replacement devices meet the same -55°C to +125°C temperature range and supply current limits.
