VCA810

SBOS275C − JUNE 2003 − REVISED OCTOBER 2004

High Gain Adjust Range, Wideband,

Voltage-Controlled Amplifier

FEATURES

DESCRIPTION

The VCA810 is a DC-coupled, wideband, continuously

HIGH GAIN ADJUST RANGE: ꢀ40dB

DIFFERENTIAL IN/SINGLE-ENDED OUT

LOW INPUT NOISE VOLTAGE: 2.4nV/ꢁ Hz

CONSTANT BANDWIDTH vs GAIN: 35MHz

HIGH dB/V GAIN LINEARITY: ꢀ0.3dB

GAIN CONTROL BANDWIDTH: 25MHz

LOW OUTPUT DC ERROR: < ꢀ40mV

HIGH OUTPUT CURRENT: ꢀ60mA

variable, voltage-controlled gain amplifier. It provides a

differential input to single-ended output conversion with a

high-impedance gain control input used to vary the gain over

a –40dB to +40dB range linear in dB/V.

Operating from 5V supplies, the gain control voltage for the

VCA810 will adjust the gain from –40dB at 0V input to +40dB

at –2V input. Increasing the control voltage above ground will

attenuate the signal path to > 80dB. Signal bandwidth and

slew rate remain constant over the entire gain adjust range.

This 40dB/V gain control is accurate within 1.5dB ( 0.9dB

for High Grade), allowing the gain control voltage in an AGC

application to be used as a Received Signal Strength

Indicator (RSSI) with 1.5dB accuracy.

LOW SUPPLY CURRENT: 24.8mA (max for

−40ꢂ C to +85ꢂ C temperature range)

Excellent common-mode rejection and common-mode input

range at the two high-impedance inputs allow the VCA810 to

provide a differential receiver operation with gain adjust. The

output signal is referenced to ground. Zero differential input

voltage gives a 0V output with a small DC offset error. Low

input noise voltage ensures good output SNR at the highest

gain settings.

APPLICATIONS

OPTICAL RECEIVER TIME GAIN CONTROL

SONAR SYSTEMS

VOLTAGE-TUNABLE ACTIVE FILTERS

LOG AMPLIFIER

In applications where pulse edge information is critical, and

the VCA810 is being used to equalize varying channel loss,

minimal change in group delay over gain setting will retain

excellent pulse edge information.

AGC RECEIVER WITH RSSI

IMPROVED REPLACEMENT FOR THE

VCA610

An improved output stage provides adequate output current

to drive the most demanding loads. While principally intended

to drive analog-to-digital converters (ADCs) or 2nd-stage

amplifiers, the 60mA output current will easily drive

doubly-terminated 50Ω lines or a passive post filter stage

over the 1.7V output voltage range.
