Quad exponential voltage controlled Amlifier
AS2164 - Quad voltage exponentially controlled amplifier (VCA)
|AS2164 contains four independent
voltage controlled amplifiers (VCAs) in a single package. High
performance (100 dB dynamic range, 0.02% THD) is provided at a very low
cost-per-VCA, resulting in excellent value for cost sensitive gain
control applications. Each VCA offers current input and output for
maximum design flexibility, and a ground referenced –33 mV/dB control
All channels are closely matched to within 0,07 dB at unity
gain, and 0,24 dB at 40 dB of attenuation. A 120 dB gain range is
A single resistor tailors operation between full Class A
and AB modes.
AS2164 is internally protected in situations where
negative supply is turned OFF.
The AS2164 will operate over a wide
supply voltage range of ±4 V to ±18 V. Available in 16-pin PDIP and SOIC
