DESCRIPTION
The LTC
over a wide voltage range of 7V to 80V. In default operation
mode, the onboard 12-bit ADC continuously measures
high side current, input voltage and an external voltage.
Data is reported through the I
by a host. The LTC4151 can also perform on-demand
measurement in a snapshot mode. The LTC4151 features
a dedicated shutdown pin to reduce power consumption.
The LTC4151-1/LTC4151-2 feature split I
drive opto-isolators. The data out on the LTC4151-1 is
inverted while that on the LTC4151-2 is not.
