GENERAL DESCRIPTION

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

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. 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,

the device is guaranteed for operation over the extended

industrial temperature range of –40°C to +85°C.

SSM2164在单封装中集成了四个独立电压控制放大器(VCA)。该器件具有高性能（100 dB动态范围，总谐波失真0.02%），且每个VCA成本极低，能为成本敏感型增益控制应用带来出色的价值。每个VCA均提供电流输入和输出，能提供极高的设计灵活性，此外还具有对地参考的-33 mV/dB控制端口。

所有通道均严格匹配，匹配程度达到单位增益时的0.07 dB范围内，40 dB衰减时为0.24 dB。可以实现120 dB的增益范围。

单电阻可以定制整个A级和AB模式之间的操作。引脚排列允许以少的额外电路完成SSM2024设计升级。

SSM2164可在±4 V至±18 V的宽电源电压范围内工作，提供16引脚P-DIP和SOIC封装，保证工作温度范围为-40°C至+85°C扩展工业温度范围。
