Description
1
OUTA
Open Drain Output for comparator A. Capable of sinking up to 40mA of current.
2
INA_U
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.
3
INA_L
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.
4
GND
Ground
5
INB_L
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.
6
INB_U
Monitors Analog Input Voltage on comparator B. 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 B. The other input of comparator B is connected to a
400mV reference.
7
Vs
Power Supply. Operates from 1.7V to 5.5V.
8
OUTB
Open Drain Output for comparator B. Capable of sinking up to 40mA of current.
