... ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the human body and test equipment and can discharge without detection. Although the SSM2164 features proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation or loss of functionality ...

... With 15 V supplies 7.5k gives Class A biasing with a B current of 1.9 mA. Leaving the MODE pin open sets the SSM2164 in Class AB with current in the gain core. Basic VCA Configuration Figure 24 shows the basic application circuit for the SSM2164. Each of the four channels is configured identically resistor converts the input voltage to an input current for the VCA ...

... Since the SSM2164 has a –33 mV/dB gain con- stant, the overall control law is 0.12 dB/bit or approximately 8 bits/dB. The input and output configuration for the SSM2164 is the same as for the basic VCA circuit shown earlier. The 4-to-1 mixer configuration could also be used. +15V ...

... Since both parts are current output devices, the output configu- ration is nearly identical, except that the 10 k resistors should be increased operate the SSM2164 in its optimum range. The 10 k input resistor for the SSM2024 should also be increased match the output resistor. Addition- ally, the 200 series with 560 pF for the SSM2164 circuit ...
