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

AMC1305M05QDWRQ1 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 | NC | unconnected | This pin can be connected to AVDD or can be left unconnected. |
| 2 | AINP | input | Noninverting analog input of the modulator, to be driven from the shunt resistor (input range ±50 mV for the M05 version). |
| 3 | AINN | input | Inverting analog input of the modulator, connected to the low side of the shunt resistor. |
| 4 | AGND | power_in | This pin is internally connected to pin 8 and can be left unconnected or tied to high-side ground. |
| 5 | NC | unconnected | This pin can be left unconnected or tied to AGND only. |
| 6 | NC | unconnected | This pin has no internal connection. |
| 7 | AVDD | power_in | High-side power supply, 4.5 V to 5.5 V (5.0 V nominal); decouple per the Power-Supply Recommendations section. |
| 8 | AGND | power_in | High-side ground reference, internally connected to pin 4. |
| 9 | DGND | power_in | Controller-side ground reference. |
| 10 | NC | unconnected | No internal connection on the AMC1305Mx-Q1 CMOS version (DOUT_N is only used on the AMC1305L25-Q1 LVDS version). |
| 11 | DOUT | output | Modulator bitstream data output (CMOS interface). |
| 12 | NC | unconnected | No internal connection on the AMC1305Mx-Q1 CMOS version (CLKIN_N is only used on the AMC1305L25-Q1 LVDS version). |
| 13 | CLKIN | input | Modulator clock input, 5 MHz to 20.1 MHz. |
| 14 | DVDD | power_in | Controller-side power supply, 3.0 V to 5.5 V (3.3 V nominal). |
| 15 | NC | unconnected | This pin can be left unconnected or tied to DVDD only. |
| 16 | DGND | power_in | Controller-side ground reference. |
