Modulators Boast Of High Accuracy

June 1, 1999

With up to ±0.1% full scale linearity, this new series of high-accuracy modulators are designed to convert dc input signals to linearly proportional ac output signals. Accepting ±10 or ±100 vdc inputs and providing an ac output of 0 to 7 Vrms, the modulators have an output impedance of only 11/2 maximum and are insensitive to ±10% reference line changes. Any ac output voltage can be provided via internal or external transformers, and the output is short-circuit protected. Gain and zero adjustments are standard.
