AMC3301DWER from Texas Instruments, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 DCDC_OUT power_out High-side output of the isolated DC/DC converter. Connect this pin to the HLDO_IN pin. Provides the raw isolated supply that feeds the on-chip high-side LDO.
2 DCDC_HGND power_in High-side power ground reference for the isolated DC/DC converter. Connect this pin to the HGND pin.
3 HLDO_IN power_in Input of the high-side LDO. Connect this pin to the DCDC_OUT pin. Requires decoupling per Power Supply Recommendations.
4 NC unconnected No internal connection. Connect this pin to HGND or leave this pin unconnected.
5 HLDO_OUT power_out Output of the high-side LDO. Provides the regulated high-side supply used by the isolated input amplifier; requires decoupling capacitor to HGND.
6 INP input Noninverting analog input. Either INP or INN must have a DC current path to HGND to define the common-mode input voltage. Differential full-scale input range ±250 mV; clipping at ±320 mV.
7 INN input Inverting analog input. Either INP or INN must have a DC current path to HGND to define the common-mode input voltage.
8 HGND power_in High-side analog signal ground. Connect this pin to the DCDC_HGND pin. Reference for the high-side (isolated) analog input circuitry.
9 GND power_in Low-side analog signal ground. Connect this pin to the DCDC_GND pin. Reference for the low-side (system-side) analog output circuitry.
10 OUTN output Inverting analog output. Together with OUTP provides a differential output centered at VDD/2 with fixed gain of 8.2 from the isolated input.
11 OUTP output Noninverting analog output. Together with OUTN provides a differential output centered at VDD/2 with fixed gain of 8.2 from the isolated input.
12 VDD power_in Low-side power supply. Recommended 3.0 V to 5.5 V (nominal 3.3 V). Requires decoupling capacitor to GND per Power Supply Recommendations.
13 LDO_OUT power_out Output of the low-side LDO. Connect this pin to the DCDC_IN pin. The output of the LDO must not be loaded by external circuitry.
14 DIAG 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_in Low-side ground reference for the isolated DC/DC converter. Connect this pin to the GND pin.
16 DCDC_IN power_in Low-side input of the isolated DC/DC converter. Connect this pin to the LDO_OUT pin.
