MCP4726A2T-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 DAC voltage output that swings from approximately 0V to approximately VDD, with a full-scale range of VSS to G × VREF and about 1Ω DC output impedance in Normal mode. |
| 2 | VSS | power_in | Ground reference pin for all circuitry on the device, which must be connected to a low-impedance ground plane. |
| 3 | VDD | power_in | Positive supply voltage input, relative to VSS, specified for 2.7V to 5.5V operation and recommended to be bypassed with about 0.1 µF ceramic plus 10 µF tantalum capacitors. |
| 4 | SDA | bidirectional | I2C serial data pin, an open-drain N-channel driver that requires a pull-up resistor from VDD and must only change state while SCL is low (except for Start and Stop conditions). |
| 5 | SCL | input | I2C serial clock input that accepts only external clocks from the master, with an open-drain N-channel driver that requires a pull-up resistor from VDD. |
| 6 | VREF | power_in | External voltage reference input that can be selected as the resistor ladder reference instead of VDD, optionally buffered, and limited to a maximum of VDD/2 when the output gain is 2. |
