Catalog excerpts

Small Instrumentation Modules SIM980 — Analog summing amplifier (4-channel) • Four summing inputs • 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/us, and input offsets that are trimmed to ±100 uV, the SIM980 is extremely useful in many analog applications. 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.
