DC1208A

DC1208A demonstration circuit features the LTC4151 high side power monitor that accepts input voltages from 7V to 80V. In default operation mode, the onboard 12bit ADC continuously measures high side current, input voltage and an external voltage. Data is reported through the I2C interface when polled by a host. The monitors can also perform on-demand measurement in a snapshot mode. The LTC4151 features a dedicated shutdown pin to reduce power consumption. DC1208A has jumpers on ADR1 and ADR0 to select one of nine distinct I2C addresses. A shut down jumper enables the LTC4151 or disables it into a low current shutdown state. I2C communication can be performed through the QuickEval system for evaluation of the part. DC1208A can also be used in an assembly option with the LTC4151-1 which features split I2C data pins with data in and an inverted output to drive opto-isolators.
