com VCA2617 SBOS326 −AUGUST 2005 Dual, Variable Gain Amplifier FEATURES D INDEPENDENT CHANNEL CONTROLS: − Gain Range: 48dB − Clamping Levels − Post-Gain: 0, +6dB DESCRIPTION The VCA2617 is a dual-channel, continuously variable, voltage-controlled gain amplifier well-suited for a variety of ultrasound systems as well as applications in proximity detectors and test equipment.
The VCA2617 uses a true variable-gain amplifier architecture, achieving very good noise performance at low gains, while not sacrificing high gain distortion performance.
Following a linear-in-dB response, the VCA2617 gain can be varied over a 48dB range with a 0.
2V to 2.
