Description

IC OP-AMP VGA 710MHZ SGL 14SOIC
The VCA821 device is a DC-coupled, wideband, linear in dB, continuously variable, voltage-controlled gain amplifier. It provides a differential input to singleended conversion with a high-impedance gain control input used to vary the gain down 40 dB from the nominal maximum gain set by the gain resistor (RG) and feedback resistor (RF). The VCA821 device 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 6 dB and 32 dB. Operating from ±5-V supplies, the gain control voltage for the VCA821 device adjusts the gain linearly in dB as the control voltage varies from 0V to +2 V. For example, set at a maximum gain of 20 dB, the VCA821 device provides 20 dB, at VG = +2 V, to less than –20 dB at VG = 0 V. The VCA821 device offers excellent gain linearity. For a 20-dB maximum gain, and a gain-control input voltage varying between +1 V and +2 V, the gain does not deviate by more than ±0.3 dB (maximum at +25°C).
