# AMC1204QDWRQ1

**Texas Instruments** · ADCs/DACs - Special Purpose · SOIC-16-300mil

AMC1204QDWRQ1 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 power supply for the isolated modulator side. |
| 2 | VINP | input | Noninverting analog input of the differential shunt-voltage input. |
| 3 | VINN | input | Inverting analog input of the differential shunt-voltage input. |
| 4 | AGND | power_in | High-side ground; pins 4 and 8 are connected internally via 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; internally connected to pin 4 via a low-impedance path, so only one of pins 4 and 8 must be tied to the ground plane. |
| 9 | DGND | power_in | Controller-side ground; internally connected to pin 16, so only one of the two pins must be tied to the ground plane. |
| 10 | NC | unconnected | No internal connection; can be tied to any potential or left unconnected. |
| 11 | DATA | output | Modulator 1-bit data output, referenced to the controller-side supply and ground (DVDD/DGND). |
| 12 | NC | unconnected | No internal connection; can be tied to any potential or left unconnected. |
| 13 | CLKIN | input | Modulator clock input, up to 20 MHz, with tHIGH and tLOW limited to 20 to 120 ns. |
| 14 | DVDD | power_in | Controller-side power supply for the digital interface. |
| 15 | NC | unconnected | No internal connection; can be tied to any potential or left unconnected. |
| 16 | DGND | power_in | Controller-side ground; internally connected to pin 9, so only one of the two pins must be tied to the ground plane. |
