**Texas Instruments** · Analog To Digital Converters (ADCs) · SOIC-16-300mil

AMC3306M25DWER from Texas Instruments, in a SOIC-16-300mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | DCDC_OUT | power_out | High-side output of the DC/DC converter; connect this pin to the HLDO_IN pin. |
| 2 | DCDC_HGND | power_in | High-side ground reference for the 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. |
| 4 | NC | unconnected | No internal connection; connect this pin to the high-side ground or leave unconnected (floating). |
| 5 | HLDO_OUT | power_out | Output of the high-side LDO. |
| 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, with specified linear differential full-scale of ±250 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, with specified linear differential full-scale of ±250 mV. |
| 8 | HGND | power_in | High-side analog signal ground; connect this pin to the DCDC_HGND pin. |
| 9 | GND | power_in | Low-side analog signal ground; connect this pin to the DCDC_GND pin. |
| 10 | DOUT | output | Modulator data output, with voltage range GND - 0.5 V to VDD + 0.5 V absolute maximum. |
| 11 | CLKIN | input | Modulator clock input with internal pulldown resistor (typical 1.5 MΩ), specified for 5 MHz to 21 MHz input clock frequency. |
| 12 | VDD | power_in | Low-side power supply, specified from 3 V to 5.5 V relative to GND (3.3 V nominal). |
| 13 | LDO_OUT | power_out | Output of the low-side LDO; connect this pin to the DCDC_IN pin and do not load it with external circuitry. |
| 14 | DIAG | output | Active-low, open-drain status indicator output; connect to the pullup supply (for example, VDD) through a resistor or leave floating if not used, with 6.5 V absolute maximum. |
| 15 | DCDC_GND | power_in | Low-side ground reference for the DC/DC converter; connect this pin to the GND pin. |
| 16 | DCDC_IN | power_in | Low-side input of the DC/DC converter; connect this pin to the LDO_OUT pin. |
