Analog Front-End Supply

4.1 Analog Front-End Supply
The analog front end of the EVM includes six OPA2132 operational amplifiers.
These amplifiers are powered through J7 and are configured for bipolar
operation. The circuits are designed to operate from a maximum supply
voltage of
±
12 VDC. Single supply operation can be achieved by applying a
positive dc voltage to pin 1 of J7 (marked as +12 V on EVM) while applying a
ground reference to both pins 2 and 3.
