# AMC1303M0520DWVR

**Texas Instruments** · ADCs/DACs - Special Purpose · SOIC-8-300mil

AMC1303M0520DWVR 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) supply, 3.0 V to 5.5 V; decoupling is described in the Power Supply Recommendations section. |
| 2 | AINP | input | Non-inverting analog input; the linear full-scale range is ±250 mV for AMC1303x25x and ±50 mV for AMC1303x05x. |
| 3 | AINN | input | Inverting analog input; the linear full-scale range is ±250 mV for AMC1303x25x and ±50 mV for AMC1303x05x. |
| 4 | AGND | power_in | Analog (high-side) ground reference for the isolated front end. |
| 5 | DGND | power_in | Digital (controller-side) ground reference. |
| 6 | DOUT | output | Modulator bitstream output; on the AMC1303Mx this is the uncoded bitstream synchronized to CLKOUT. |
| 7 | CLKOUT | output | Modulator clock output, nominal 10 MHz on AMC1303Mxx10 or 20 MHz on AMC1303Mxx20 (AMC1303M0520 is the 20 MHz version); not present on the AMC1303Ex, where this pin is tied to DGND. |
| 8 | DVDD | power_in | Digital (controller-side) supply, 2.7 V to 5.5 V; decoupling is described in the Power Supply Recommendations section. |
