Description

1

OUTA

Open-Drain Output for Comparator A.

2

±INA_U

Monitors Analog Input Voltage on Comparator A. Connect to the upper tap point of the resistor string. Connect

internally to the noninverting input on the ADCMP341 or the inverting pin on the ADCMP343 via a mux controlled

by the output level on Comparator A. The other input of Comparator A is connected to a 400 mV reference.

3

±INA_L

Monitors Analog Input Voltage on Comparator A. Connect to the lower tap point of the resistor string. Connect

internally to the noninverting input on the ADCMP341 or the inverting pin on the ADCMP343 via a mux controlled

by the output level on Comparator A. The other input of Comparator A is connected to a 400 mV reference.

4

GND

Ground.

5

±INB_L

Monitors Analog Input Voltage on Comparator B. Connect to the lower tap point of the resistor string. Connect

internally to the noninverting input on the ADCMP341 or the inverting pin on the ADCMP343 via a mux controlled

by the output level on Comparator B. The other input of Comparator B is connected to a 400 mV reference.

6

±INB_U

Monitors Analog Input Voltage on Comparator B. Connect to the upper tap point of the resistor string. Connect

internally to the noninverting input on the ADCMP341 or the inverting pin on the ADCMP343 via a mux controlled

by the output level on Comparator B. The other input of Comparator B is connected to a 400 mV reference.

7

Power Supply Pin.

8

OUTB

Open-Drain Output for Comparator B.
