Ultra-Wideband, > 40dB Gain Adjust Range, Linear in V/V

VARIABLE GAIN AMPLIFIER

FEATURES

DESCRIPTION

•

710MHz SMALL-SIGNAL BANDWIDTH

(G = +2V/V)

The VCA824 is a dc-coupled, wideband, linear in V/V,

continuously variable, voltage-controlled gain

amplifier. It provides differential input to

single-ended conversion with a high-impedance gain

control input used to vary the gain down 40dB from

the nominal maximum gain set by the gain resistor

(R_G) and feedback resistor (R_F).

•

320MHz, 4V_PPBANDWIDTH (G = +10V/V)

0.1dB GAIN FLATNESS to 135MHz

2500V/µs SLEW RATE

•

> 40dB GAIN ADJUST RANGE

HIGH GAIN ACCURACY: 20dB ±0.3dB

HIGH OUTPUT CURRENT: ±90mA

The VCA824 internal architecture consists of two

input buffers and an output current feedback amplifier

stage integrated with a multiplier core to provide a

complete variable gain amplifier (VGA) system that

does not require external buffering. The maximum

gain is set externally with two resistors, providing

flexibility in designs. The maximum gain is intended

to be set between +2V/V and +40V/V. Operating from

±5V supplies, the gain control voltage for the VCA824

adjusts the gain linearly in V/V as the control voltage

varies from +1V to –1V. For example, set for a

maximum gain of +10V/V, the VCA824 provides

10V/V, at +1V input, to 0.1V/V at –1V input of gain

control range. The VCA824 offers excellent gain
