Current-Mode Multiplier

Features

# Flexible inputs and outputs, all

ground referred

General Description

The EL2082 is a general purpose variable gain control building

block, built using an advanced proprietary complementary bi-

polar process. It is a two-quandrant multiplier, so that zero or

negative control voltages do not allow signal feedthrough and

very high attenuation is possible. The EL2082 works in current

mode rather than voltage mode, so that the input impedance is

low and the output impedance is high. This allows very wide

bandwidth for both large and small signals.

# 150 MHz large and small-signal

bandwidth

# 46 dB of calibrated gain control

range

# 70 dB isolation in disable mode

10 MHz

# 0.15% diff gain and 0.05 diff

The I pin replicates the voltage present on the V pin; there-

fore, the V pin can be used to reject common-mode noise and

phase performance at NTSC

using application circuit

establish an input ground reference. The gain control input is

calibrated to 1 mA/mA signal gain for 1V of control voltage.

The disable pin (E) is TTL-compatible, and the output current

can comply with a wide range of output voltages.

# Operates on 5V to 15V power

supplies

# Outputs may be paralleled to

function as a multiplexer

Because current signals rather than voltages are employed, mul-

tiple inputs can be summed and many outputs wire-or’ed or

mixed.

Applications

# Level adjust for video signals

# Video faders and mixers

# Signal routing multiplexers

# Variable active filters

# Video monitor contrast control

# AGC

The EL2082 operates from a wide range of supplies and is avail-

able in standard 8-pin plastic DIP or 8-lead SO.
