PRINCIPLE FUNCTION
Adjustable amplification of differential voltage signals (
±
5 to
±
100mV FS)
to an adjustable, ratiometric output voltage of between
0.2 and Vcc-0.2Volt with a diagnostic unit
TYPICAL APPLICATIONS
Precision amplifiers for bridge circuits with
low sensitivity:
for ceramic measurement cells
for DMS sensing elements
for GMR sensing elements
Sensor amplification with functional control
