Pin No. Mnemonic 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.
