AMC1204DWR 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 | AVDD | power_in | High-side (analog) power supply, recommended 4.5 V to 5.5 V (5 V nominal) referenced to AGND, with an absolute maximum of 6 V. |
| 2 | VINP | input | Noninverting analog input for the differential shunt-voltage input, with a ±250 mV input range and absolute limits of AGND - 0.5 V to AVDD + 0.5 V. |
| 3 | VINN | input | Inverting analog input for the differential shunt-voltage input, connected to the negative end of the shunt, with absolute limits of AGND - 0.5 V to AVDD + 0.5 V. |
| 4 | AGND | power_in | High-side ground reference for the analog domain; pins 4 and 8 are connected internally through a low-impedance path, so only one of them must be tied to the ground plane. |
| 5 | NC | unconnected | No internal connection; can be tied to any potential or left unconnected. |
| 6 | NC | unconnected | No internal connection; can be tied to any potential or left unconnected. |
| 7 | NC | unconnected | No internal connection; can be tied to any potential or left unconnected. |
| 8 | AGND | power_in | High-side ground reference for the analog domain; connected internally to pin 4 through a low-impedance path, so only one of the two AGND pins must be tied to the ground plane. |
| 9 | DGND | power_in | Controller-side (digital) ground reference for the isolated digital interface. |
| 10 | NC | unconnected | No internal connection; can be tied to any potential or left unconnected. |
| 11 | DATA | output | Modulator 1-bit data output, providing the isolated digital bitstream to the controller or digital filter. |
| 12 | NC | unconnected | No internal connection; can be tied to any potential or left unconnected. |
| 13 | CLKIN | input | Modulator clock input for the digital interface, with absolute limits of DGND - 0.3 V to DVDD + 0.3 V and a clock frequency up to 20 MHz. |
| 14 | DVDD | power_in | Controller-side (digital) power supply, recommended 2.7 V to 5.5 V (3.3 V nominal) referenced to DGND, with an absolute maximum of 6 V. |
| 15 | NC | unconnected | No internal connection; can be tied to any potential or left unconnected. |
| 16 | DGND | power_in | Controller-side (digital) ground reference, connected alongside pin 9 as the DGND return. |
