# AMC1203DWR

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

AMC1203DWR 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 | Analog (high-side) power supply, specified at 4.5 V to 5.5 V (5.0 V nominal) from AVDD to AGND, and should be decoupled per the Power Supply Recommendations section. |
| 2 | INP | input | Noninverting analog input for the differential input VIN = VINP − VINN, with a specified linear range of −280 mV to 280 mV and clipping above ±320 mV. |
| 3 | INN | input | Inverting analog input for the differential input VIN = VINP − VINN, with a specified linear range of −280 mV to 280 mV and clipping above ±320 mV. |
| 4 | AGND | power_in | Analog (high-side) ground reference; pins 4 and 8 are connected internally by a low-impedance path, so only one must be tied to the ground plane. |
| 5 | NC | unconnected | No internal connection; tie to any potential or leave unconnected. |
| 6 | NC | unconnected | No internal connection; tie to any potential or leave unconnected. |
| 7 | NC | unconnected | No internal connection; tie to any potential or leave unconnected. |
| 8 | AGND | power_in | Analog (high-side) ground; connected internally to pin 4 by a low-impedance path, so only one of the two pins must be tied to the ground plane. |
| 9 | DGND | power_in | Digital (low-side) ground; connected internally to pin 16 by a low-impedance path, so only one of the two pins must be tied to the ground plane. |
| 10 | NC | unconnected | No internal connection; tie to any potential or leave unconnected. |
| 11 | DOUT | output | Modulator data output, a bitstream synchronized to the internally generated clock. |
| 12 | NC | unconnected | No internal connection; tie to any potential or leave unconnected. |
| 13 | CLKOUT | output | Modulator clock output derived from the internal 10 MHz clock generator. |
| 14 | DVDD | power_in | Digital (low-side) power supply, specified at 4.5 V to 5.5 V (5.0 V nominal) from DVDD to DGND, and should be decoupled per the Power Supply Recommendations section. |
| 15 | NC | unconnected | No internal connection; tie to any potential or leave unconnected. |
| 16 | DGND | power_in | Digital (low-side) ground; connected internally to pin 9 by a low-impedance path, so only one of the two pins must be tied to the ground plane. |
