Description
Open Drain Output for comparator A. Capable of sinking up to 40mA of current.
Monitors Analog Input Voltage on comparator A. Connect to the upper tap point of the resistor string.
Connected internally to the noninverting input on the ADCMP341 or the inverting pin on the ADCMP343
via mux controlled by output level on comparator A. The other input of comparator A is connected to a
400mV reference.
Monitors Analog Input Voltage on comparator A. Connect to the lower tap point of the resistor string.
Connected internally to the noninverting input on the ADCMP341 or the inverting pin on the ADCMP343
via mux controlled by output level on comparator A. The other input of comparator A is connected to a
400mV reference.
Ground
Monitors Analog Input Voltage on comparator B. Connect to the lower tap point of the resistor string.
Connected internally to the noninverting input on the ADCMP341 or the inverting pin on the ADCMP343
via mux controlled by output level on comparator B. The other input of comparator B is connected to a
400mV reference.
Monitors Analog Input Voltage on comparator B. Connect to the upper tap point of the resistor string.
