AD8072ARMZ

Overview

The AD8072ARMZ is a dual current feedback video amplifier manufactured by Analog Devices Inc. It operates within a supply voltage range of ±2.5 V to ±6 V (single 5 V to 12 V). Key electrical parameters include a –3 dB bandwidth of 100 MHz at a gain of +2, a slew rate of 500 V/µs, and a settling time of 25 ns to 0.1%. The device consumes 3.5 mA per amplifier and provides 30 mA output current. It features an input offset voltage of 4 mV and input bias current of 10 µA. The component is housed in an 8-lead µSOIC package and supports an industrial temperature range from –40 °C to +85 °C.

Feature Summary

• Low cost design optimized for high volume applications
• Good video specifications including 0.05% differential gain error
• Low power consumption with 3.5 mA per amplifier supply current
• High speed performance with 100 MHz bandwidth

Applications

• Video line driver
• Computer video plug-in boards
• RGB or S-video amplifier in component systems

Procurement Notes

Verify the specific ordering suffix to confirm the packaging format, as the base model may be available in tubes while suffixes like REEL7 indicate tape and reel quantities. Confirm the industrial temperature grade (-40°C to +85°C) matches the application requirements, as commercial variants exist. Ensure ESD precautions are observed during handling due to the sensitivity of the internal circuitry.

Selection Notes

Select this component for cost-sensitive designs requiring solid video performance into 150 Ω loads. It is suitable for applications needing single 5 V to 12 V operation with outputs swinging to within 1.3 V of the rails. Consider the 8-lead µSOIC package for space-constrained layouts. Verify that the required feedback resistor values remain between 649 Ω and 2 kΩ to maintain gain flatness.

Part Context

The AD8072 is part of a family of low-cost, current feedback amplifiers intended for business and consumer video electronics. It shares characteristics with the AD8073 triple amplifier but offers two accessible channels in an 8-lead package. The device is designed to drive back-terminated video loads efficiently while maintaining high speed and low power consumption.

Replacement Considerations

Check for availability of the AD8072JR or AD8072JN if commercial temperature range (0°C to 70°C) suffices. Verify pin compatibility when substituting with other dual video amplifiers from the manufacturer's portfolio.
