SA9108F
2. Analog Input Configuration
The current and voltage sensor inputs are illustrated below.
These inputs are protected against electrostatic discharge through clamping
diodes, in conjunction with the amplifiers input configuration.
The feedback loops from the outputs of the amplifiers A and A generate virtual

shorts on the signal inputs. Exact duplications of the input currents are generated
for the analog processing circuitry.
