The SIM983 Scaling Amplifier provides fine adjustable gain and offset control for analog signals.
Both gain and offset are set with 3½ digits of resolution, and the signal path has more than 1 MHz of bandwidth.
Its low noise, high gain, and high slew rate make the SIM983 a very convenient tool for sensitive analog signal conditioning.
The digital control circuitry in the SIM983 is designed with SRS's special clock-stopping architecture in which the microcontroller is turned on only when switch settings are being changed.
This guarantees that no digital noise contaminates low-level analog signals.
