AS2164

AS2164 - Quad voltage exponentially controlled amplifier (VCA) PDIP-16 Package
Manufacturer: ALFA RPAR
SKU: IM-AS2164-IC
Ђ6.17

AS2164 contains four independent voltage controlled amplifiers (VCAs) in a single package. High performance (dynamic range 100 dB) provides excellent use of VCA's in gain control applications. Each VCA offers current inputs and outputs for maximum design flexibility, as well as a –33 mV/ dB ground control port.

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 possible.

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.
