AMC1303M2520DWVR from Texas Instruments, in a SOIC-8-300mil. 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 | Analog (high-side) power supply, 3.0V to 5.5V; see the Power Supply Recommendations section for decoupling. |
| 2 | AINP | input | Noninverting analog input of the modulator. |
| 3 | AINN | input | Inverting analog input of the modulator. |
| 4 | AGND | power_in | Analog (high-side) ground reference. |
| 5 | DGND | power_in | Digital (controller-side) ground reference. |
| 6 | DOUT | output | Modulator bitstream output; uncoded for the AMC1303Mx (Manchester coding applies only to the AMC1303Ex derivatives). |
| 7 | CLKOUT | output | Modulator clock output, 20MHz nominal on the AMC1303Mxx20 (10MHz on AMC1303Mxx10). |
| 8 | DVDD | power_in | Digital (controller-side) power supply, 2.7V to 5.5V; see the Power Supply Recommendations section for decoupling. |
