With
control ports, they offer wide-range exponential
control of gain and attenuation with low signal
distortion. Both VCAs are trimmed at wafer stage
to deliver low distortion and control-voltage
feedthrough
However, external symmetry adjustment is possi-
ble to further optimize distortion and control
feedthrough for critical applications.

Description
up to ±16 Vdc, drawing only 5.2mA at ±15V and
3 mA at ±5V. The part can also operate at supply
voltages as low as ±2.25V, making it suitable for
battery-operated applications.
sharing only their power supply connections.
The 2162 is extremely flexible and capable of
being configured for a wide range of stereo or
multichannel applications. It is available in a
RoHS-compliant 16-pin QSOP package.
