AS “АLFA RPAR” Joint Stock Company ALFA Riga, Latvia www.alfarzpp.lv; alfa@alfarzpp.lv 2019 v.1 1 AS2164 AS2164 - Quad voltage exponentially controlled amplifier (VCA) Features AS2164 - four high performance VCAs in a single package - 0,02% THD - 0,02% THD - no external trimming - 120 dB gain range - 0,07 dB gain matching (unity gain) - class A or AB operation - protection from negaive supply turned OFF Applications PDIP-16, 300mil, 2.54 mm - Remote, Automatic, or Computer Volume Controls - Automotive Volume/Balance/Faders AS2164D - Audio Mixers - Compressor/Limiters/Compandors - Noise Reduction Systems - Automatic Gain Controls - Voltage Controlled Filters - Special Sound Processors SOIC-16, 150mil, 1.27 mm General Description AS2164 contains four independent voltage controlled amplifiers (VCAs) in a s ingle 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 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 operat e over a wide supply voltage range of ±4 V to ±18 V.
