MCP4728-E from Microchip Tech, in a MSOP-10. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VDD | power_in | Supply voltage input (2.7V to 5.5V); used as device power supply and optional external DAC voltage reference. |
| 2 | SCL | input | I2C serial clock input (open-drain); requires external pull-up resistor (5-10 kΩ for 100-400 kHz modes, less than 1 kΩ for 3.4 MHz mode). |
| 3 | SDA | bidirectional | I2C serial data input and output (open-drain); requires external pull-up resistor (5-10 kΩ for 100-400 kHz modes, less than 1 kΩ for 3.4 MHz mode). |
| 4 | LDAC | input | Synchronization input (Schmitt trigger) for transferring DAC input register contents to output registers and selecting device for I2C address bit programming; can be driven by MCU I/O pin. |
| 5 | RDY/BSY | output | Status indicator output (open-drain) of EEPROM programming activity; high = ready, low = programming; requires external pull-up resistor (~100 kΩ). |
| 6 | VOUT A | output | Buffered analog voltage output of DAC channel A with rail-to-rail operation; can drive up to 1000 pF capacitive load with recommended load resistance of at least 5 kΩ. |
| 7 | VOUT B | output | Buffered analog voltage output of DAC channel B with rail-to-rail operation; can drive up to 1000 pF capacitive load with recommended load resistance of at least 5 kΩ. |
| 8 | VOUT C | output | Buffered analog voltage output of DAC channel C with rail-to-rail operation; can drive up to 1000 pF capacitive load with recommended load resistance of at least 5 kΩ. |
| 9 | VOUT D | output | Buffered analog voltage output of DAC channel D with rail-to-rail operation; can drive up to 1000 pF capacitive load with recommended load resistance of at least 5 kΩ. |
| 10 | VSS | power_in | Ground reference and device current return path; should be connected to analog ground plane through low-impedance connection. |
