A "
Voltage Controlled Element" from
Solid State Micro Technology for Music, Inc.
From the original data sheet:
The SSM 2014 is a
generalized VCA building block which will
substitute for any VCA
circuit presently
available, in
addition to possessing powerful
features not available using any other
device.
Features:
(used as a standard VCA)
116dB dynamic range (Class AB)
12MHz effective gain bandwidth product
low cost
100dB open loop gain
minimum external component count
no trimming required in many applications
0.01% Class A THD (any gain or 8signal], +10dBV in/out)
Class A or AB operation
Unique Features:
replaces any VCA in any application
combines all features of Op Amps and VCAs
acts as a voltage controlled potentiometer
complementary outputs
acts as a voltage controlled preamp
has high and low (balanced) impedance inputs
fully buffered control port
voltage selectable Class A or AB operation
