VCA2617 2 通道可变增益放大器
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 2.3V control voltage. Two separate high-impedance control inputs allow for a channel independent variation of the gains. Each channel of the VCA2617 can be configured to provide a gain range of -10dB to 38dB, or -16dB to 32dB, depending on the gain select pin (HG)\.
