VCA-2162 VCA volume control/buffer circuit, -80 / +40dB
The attenuation/gain is regulated by a quality IC.
- THAT2162 Voltage Controlled Amplifier SMD IC.
- Current driven output buffer (dual opamp IC).
- Even a Burson Dual fits !
- Controlled by a 0-5Vdc signal (gain -80 / +10dB) or
- Option: Digital SPI data (gain -80 / +40dB, 8 bit, 256 steps).
- -80 - +40mV output > digital -80.0 - 40.0dB reading 200mV meter.
- Fits directly on all our preamplifier designs, transferring them from a passive preamp to an active one.
