SA9105A
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 AI and AV generate virtual
shorts on the signal inputs. Exact duplications of the input currents are generated
for the analog processing circuitry

3. Electrostatic Discharge (ESD) Protection
TheSA9105Aintegratedcircuit'sinputs/outputsareprotectedagainstESDaccording
to Mil-Std 883 method 3015. The SA9105A integrated circuit's resistance to
transients is also dependant upon the external protection components used.
4. Power Consumption
The overall power consumption rating of the SA9105A integrated circuit is less than
75mW with a 5V supply.
