VCA820ID Datasheet PDF - TI

●DESCRIPTION

●The VCA820 is a dc-coupled, wideband, linear in dB, continuously variable, voltage-controlled gain

●amplifier. It provides a 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 (RG) and feedback resistor (RF).

●FEATURES

●• 150MHz SMALL-SIGNAL BANDWIDTH

●• 137MHz, 5VPP BANDWIDTH (G = +10V/V)

●• 0.1dB GAIN FLATNESS to 28MHz

●• 1700V/μs SLEW RATE

●• > 40dB GAIN ADJUST RANGE

●• HIGH GAIN ACCURACY: 20dB ±0.4dB
