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 integrated isolated DC/DC converter. Connect this pin to the HLDO_IN pin. Requires decoupling per the datasheet Power Supply Recommendations. |+| 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 regulator. Connect this pin to the DCDC_OUT pin. |+| 4 | NC | unconnected | No internal connection. Connect this pin to HGND or leave it unconnected. |+| 5 | HLDO_OUT | power_out | Output of the high-side LDO regulator. Requires decoupling per the Power Supply Recommendations. |+| 6 | INP | input | Noninverting analog input of the isolated amplifier. Either INP or INN must have a DC current path to HGND to define the common-mode input voltage. Specified linear full-scale differential range is ±250 mV. |+| 7 | INN | input | Inverting analog input of the isolated amplifier. 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 ground reference. Connect this pin to the DCDC_HGND pin. |+| 9 | GND | power_in | Low-side analog ground reference. Connect this pin to the DCDC_GND pin. |+| 10 | OUTN | output | Inverting analog output of the isolated amplifier. Provides the low-side, differential representation of the isolated input signal (gain = 8.2) referenced to VDD/2. |+| 11 | OUTP | output | Noninverting analog output of the isolated amplifier. Provides the low-side, differential representation of the isolated input signal (gain = 8.2) referenced to VDD/2. |+| 12 | VDD | power_in | Low-side power supply. Operating range 3 V to 5.5 V (nominal 3.3 V or 5 V) with respect to GND. Requires decoupling per the Power Supply Recommendations. |+| 13 | LDO_OUT | power_out | Output of the low-side LDO regulator. Connect this pin to the DCDC_IN pin. The LDO output must not be loaded by external circuitry. |+| 14 | DIAG | output | Active-low, open-drain status indicator (diagnostic) output. Connect to a pull-up supply (for example VDD) via a resistor, or leave floating if unused. Absolute-max voltage is 6.5 V. |+| 15 | DCDC_GND | power_in | Low-side power 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 integrated isolated DC/DC converter. Connect this pin to the LDO_OUT pin. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-16-300mil |+| Category | Signal Isolation Devices |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `AMC3301QDWERQ1`++## CAD (KiCad official)++- Symbol: `AMC3301QDWERQ1`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOIC-16-300mil (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/gpn/amc3301-q1) (37 pp, sha256 `360930ecf509eae8`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
