Device Operation
Once the VDD1 and VDD2 power is applied to the AMC1311EVM, the analog output will be available with
a fixed gain of one and a DC offset equal to 1.44 V (typical).
An analog input signal may be applied directly at screw terminal J2. Refer to
and
for
details. The analog input range is specified at 0 to 2 V.
The analog output has a nominal gain of 1 through the AMC1311 isolation amplifier. With an input voltage
of 0 – 2 V, the nominal output is ±1 V differential. The output voltage is centered on 1.44 V providing a
convenient analog input range to the embedded ADCs of the MSP430 and TMS320C2000 series of digital
processors.
