GENERAL DESCRIPTION

The ADL5331 is a high performance, voltage-controlled

variable gain amplifier/attenuator for use in applications with

frequencies up to 1.2 GHz. The balanced structure of the signal

path maximizes signal swing, eliminates common-mode noise

and minimizes distortion while it also reduces the risk of spu-

rious feed-forward at low gains and high frequencies caused by

parasitic coupling.

The output of the high accuracy wideband attenuator is applied

to a differential transimpedance output stage. The output stage

provides a differential output at OPHI and OPLO, which must be

pulled up to the supply with RF chokes or a center-tapped balun.

The ADL5331 consumes 240 mA of current including the out-

put pins and operates off a single supply ranging from 4.75 V

to 5.25 V. A power-down function is provided by applying a

logic low input on the ENBL pin. The current consumption in

power-down mode is 250 μA.

The 50 Ω differential input system converts the applied

differential voltage at INHI and INLO to a pair of differential

currents with high linearity and good common-mode rejection.

The signal currents are then applied to a proprietary voltage-

controlled attenuator providing precise definition of the overall

gain under the control of the linear-in-dB interface. The GAIN

pin accepts a voltage from 0 V at a minimum gain to 1.4 V at a

full gain with a 40 mV/dB scaling factor over most of the range.

The ADL5331 is fabricated on an Analog Devices, Inc., pro-

prietary high performance, complementary bipolar IC process.

The ADL5331 is available in a 24-lead (4 mm × 4 mm), Pb-free

LFCSP_VQ package and is specified for operation from ambient

temperatures of −40°C to +85°C. An evaluation board is also

available.
