DAC121S101QCMK

Texas Instruments · Digital To Analog Converters (DAC) · TSOT-23-6

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.
