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.
