CLC5523

Low-Power, Variable Gain Amplifier

General Descriptions

Features

■

The CLC5523 is a low power, wideband, DC-coupled, voltage-

controlled gain amplifier. It provides a voltage-controlled gain

block coupled with a current feedback output amplifier. High

impedance inputs and minimum dependence of bandwidth on

gain make the CLC5523 easy to use in a wide range of

applications. This amplifier is suitable as a continuous gain

control element in a variety of electronic systems which benefit

from a wide bandwidth of 250MHz and high slew rate of

1800V/ms, with only 135mW of power dissipation.

Low power: 135mW

Slew rate 1800V/ms

Gain flatness 0.2dB @ 75MHz

■

Rise & fall times 2.0ns

■

Low input voltage noise 4nV/ÖHz

Applications

■

Automatic gain control

■

Voltage controlled filters

Input impedances in the megaohm range on both the signal

and gain control inputs simplify driving the CLC5523 in any

application. The CLC5523 can be configured to use pin 3 as a

low impedance input making it an ideal interface for current

inputs. By using the CLC5523’s inverting configuration in which

is driven directly, inputs which exceed the device’s input

voltage range may be used.

Frequency Response with Changes in V_g

The gain control input (V ), with a 0 to 2V input range, and a

linear-in-dB gain control, simplifies the implementation of AGC

circuits. The gain control circuit can adjust the gain as fast as

4dB/ns. Maximum gains from 2 to 100 are accurately and simply

set by two external resistors while attenuation of up to 80dB from

this gain can be achieved.

The extremely high slew rate of 1800V/ms and wide bandwidth

provides high speed rise and fall times of 2.0ns, with settling time

for a 2 volt step of only 22ns to 0.2%. In time domain applications

where linear phase is important with gain adjust, the internal cur-

rent mode circuitry maintains low deviation of delay over a wide

gain adjust range.
