HMC980LP4E Datasheet ACtive Bias Controller

Manufacturer: Analog Devices

General Description

The HMC980LP4E is an active bias controller that can automatically adjust the gate voltage of an external amplifier to achieve constant drain current.

Using an integrated controller, the HMC980LP4E allows safe power-up/power-down, and disable/enable of an external amplifier, ensuring the safe powering of the amplifier.

The HMC980LP4E can be used to bias any enhancement or depletion type Class A amplifier operating with drain voltages from 5 V to 16.5 V and drain currents up to 1.6 A, thus offering a complete biasing solution.
