SIM980 Analog Summing Amplifier

SIM980 Analog Summing Amplifier
  • Four summing inputs
  • ±10 V operating range
  • 1 MHz bandwidth
  • Low crosstalk (-80 dB)
  • <100 µV input offset
  • High slew rate
    •

The SIM980 Summing Amplifier has four input channels that can be added or subtracted from each other. The output noise is less than 60 nV/vHz, and crosstalk between channels is less than -80 dB. With a bandwidth of 1 MHz, a slew rate of 40 V/ms, and input offsets that are trimmed to ±100 µV, the SIM980 is extremely useful in many analog applications.

SIM980 specifications

The digital control circuitry in the SIM980 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.
