Description

SPICE simulation of preamplifier for digital voltmeter. This microvolt preamplifier employs in the first stage a zero-drift op amp LTC2054 and a picoampere input current LTC6090 in the second stage. The amplifier voltage gain is 100 for input +/- 700mV with a bandwidth of 120khz or 1000 for input +/- 70mV with a bandwidth of 12khz. A jumper switches between the two configurations.
