MCP4728-E

Microchip Tech · Digital To Analog Converters (DAC) · MSOP-10

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.
