DAC121S101QCMK from Texas Instruments, in a TSOT-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 | DAC analog output voltage, driven by an on-chip output amplifier that allows rail-to-rail output swing. |
| 2 | GND | power_in | Ground reference for all on-chip circuitry. |
| 3 | VA | power_in | Power supply and reference input for a single 2.7 V to 5.5 V supply, which also serves as the DAC voltage reference; should be decoupled to GND. |
| 4 | DIN | input | Serial data input; data is clocked into the 16-bit shift register on the falling edges of SCLK after SYNC falls. |
| 5 | SCLK | input | Serial clock input; data is clocked into the input shift register on the falling edges of this pin, with clock rates up to 30 MHz over the specified supply range. |
| 6 | SYNC | input | Active-low frame sync that enables the input shift register; the DAC updates on the 16th SCLK falling edge, and a rising edge before the 16th clock acts as an interrupt that causes the write to be ignored. |
