Description

Input offset voltage <5 µV
DC bias current <200 fA
Current gain of 10⁶ to 10⁸ V/A
15 fA/ƒHz input noise (10⁸ V/A)
Autozero feature
Bias voltage input

The SIM918 Current Preamplifier is ideal in applications in which the input offset voltage must be kept to a minimum. The DC voltage difference between the two inputs (current input and voltage bias) is accurately measured every 2 seconds, and is nulled. The result is a current amplifier with less than 5 µV input offset voltage. This autozeroing feature can be engaged or inhibited remotely or from the front panel, giving you flexibility in sensitive applications.
