a Low Cost Quad
Voltage Controlled Amplifier
SSM2164 FEATURES
Four High Performance VCAs in a Single Package
0.02% THD
No External Trimming
120 dB Gain Range
0.07 dB Gain Matching (Unity Gain)
Class A or AB Operation FUNCTIONAL BLOCK DIAGRAM VC IIN IIN 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. The pinout allows upgrading of SSM2024 designs with
minimal additional circuitry. IIOUT IIN VCA3 IIOUT VCA4 IIOUT VC IIN POWER SUPPLY
AND BIASING CIRCUITRY V+ GND V– MODE O 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,
the device is guaranteed for operation over the extended
industrial temperature range of –40°C to +85°C. VCA2 VC B
SO 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
control applications. Each VCA offers current input and output …
