4.3.1.
LS 804.01
The LS 804.01 is designed for DMS sensors with a signal output range extending from -5mV/V to
+5mV/V. The bridge resistors may be from 350 Ω ... 1000 Ω.
Input stages "I 1a" and "I 1b" serve to feed the DMS sensors with 5 V, input stages "I c" und "I d"
supplying the DMS sensors with 3.3V.
