ADA4805-2TRMZ-EP

Overview

The ADA4805-2TRMZ-EP is a dual-channel, high-speed voltage feedback operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail outputs and operates within a supply voltage range of 2.7 V to 10 V. The device provides a -3 dB bandwidth of 105 MHz at a gain of +1 with a slew rate of 160 V/µs. Key electrical characteristics include a maximum input offset voltage of 125 µV, a typical offset drift of 0.4 µV/°C, and an ultralow quiescent current of 500 µA per amplifier. It utilizes the proprietary XFCB process for low noise performance.

Feature Summary

• Enhanced product construction supporting defense and aerospace applications under AQEC standards
• Rail-to-rail output capability with wide common-mode input range
• Ultralow power consumption suitable for battery-powered systems
• Extended industrial temperature rating from -55°C to +125°C

Applications

• High resolution, high precision analog-to-digital converter (ADC) drivers
• Battery-powered instrumentation
• Micropower active filters
• Portable point of sales terminals
• Active radio frequency identification (RFID) readers

Procurement Notes

Verify that the ordering suffix TRMZ indicates tape and reel packaging for the 8-lead MSOP variant. Confirm the EP designation corresponds to the Enhanced Product specifications, including controlled manufacturing baselines and extended temperature ranges. Ensure compatibility with the specific application requirements regarding supply voltage and load conditions before procurement.

Selection Notes

Select this component when designing systems requiring high speed combined with low power dissipation. The dual configuration is ideal for differential signal paths or multi-channel data acquisition. Consider the 105 MHz bandwidth and 160 V/µs slew rate for driving high-resolution ADCs. The extended temperature range makes it suitable for harsh environments where standard commercial parts may fail.

Part Context

This part belongs to the ADA4805 family of low-power, low-noise amplifiers. The EP suffix denotes an Enhanced Product version designed for reliability in demanding sectors. It shares core electrical performance with the standard ADA4805-2 but offers stricter manufacturing controls and broader temperature operation. The TRMZ suffix specifies the surface-mount packaging format.
