GENERAL DESCRIPTION
E The SSM2164 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
L 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,
O 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
S modes. The pinout allows upgrading of SSM2024 designs with
minimal additional circuitry.
The SSM2164 will operate over a wide supply voltage range of
± 4 V to ± 18 V. Available in 16-pin P-DIP and SOIC packages,
B the device is guaranteed for operation over the extended
O industrial temperature range of –40°C to +85°C.
