NAME

1

DCDC_OUT

Power

High-side output of the isolated DC/DC converter; connect this pin to the HLDO_IN pin.(1)

2

DCDC_HGND Power Ground High-side ground reference for the isolated DC/DC converter; connect this pin to the HGND pin.

3

HLDO_IN

Power

Input of the high-side low-dropout (LDO) regulator; connect this pin to the DCDC_OUT pin.(1)

4

NC

—

No internal connection. Connect this pin to the high-side ground or leave this pin unconnected

(floating).

5

HLDO_OUT

Power

Output of the high-side LDO.(1)

6

INP

Analog Input

Noninverting analog input.

7

INN

Analog Input

Inverting analog input. Connect this pin to HGND.

8

HGND

Signal Ground High-side analog ground; connect this pin to the DCDC_HGND pin.

9

GND

Signal Ground Low-side analog ground; connect this pin to the DCDC_GND pin.

10

OUTN

Analog Output Inverting analog output.

11

OUTP

Analog Output Noninverting analog output.

12

VDD

Power

Low-side power supply.(1)

13

LDO_OUT

Power

Output of the low-side LDO; connect this pin to the DCDC_IN pin.(1)

14

DIAG

Digital Output

Active-low, open-drain status indicator output; connect this pin to the pullup supply (for example,

VDD) using a resistor or leave this pin floating if not used.

15

DCDC_GND

Power Ground Low-side ground reference for the isolated DC/DC converter; connect this pin to the GND pin.

16

DCDC_IN

Power

Low-side input of the isolated DC/DC converter; connect this pin to the LDO_OUT pin.(1)
