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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Texas Instruments |+| Package | SOIC-16 |+| Category | Signal Isolation Devices |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `AMC3301DWER`++## CAD (KiCad official)++- Symbol: `AMC3301DWER`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOIC-16 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/cn/lit/ds/symlink/amc3301.pdf) (40 pp, sha256 `37b3f16cfe8900f6`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
