MCP4726A1T-E

Microchip Tech · Digital To Analog Converters (DACs) · SOT-23-6

MCP4726A1T-E from Microchip Tech, in a SOT-23-6. 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 VOUT output Buffered analog voltage output of the DAC that swings from approximately 0V to approximately VDD, with about 1 Ω DC output impedance in Normal mode and a 1 kΩ, 125 kΩ or 640 kΩ pull-down in Power-Down mode.
2 VSS power_in Ground reference for all circuitry on the device, to be connected to a ground plane (preferably analog ground) through a low-impedance connection.
3 VDD power_in Positive supply input (2.7V to 5.5V) relative to VSS, to be bypassed with about 0.1 µF ceramic in parallel with 10 µF tantalum placed within 4 mm of the pin.
4 SDA bidirectional I2C serial data pin with an open-drain N-channel driver that needs a pull-up resistor to VDD, and data must be stable while SCL is high except for Start and Stop conditions.
5 SCL input I2C serial clock input (open-drain, slave-only device accepting only external clocks) that needs a pull-up resistor to VDD, supporting 100 kHz, 400 kHz and 3.4 MHz modes.
6 VREF power_in External voltage reference input selectable as the DAC reference (buffered or unbuffered, with gain 1x or 2x limited to VDD/2 maximum at 2x), and disconnected from the internal circuit when VDD is selected as reference.
