Slkor SLKORMICRO Elec · Analog To Digital Converters (ADC) · SOT-23-6
SL121S021 from Slkor SLKORMICRO Elec, 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 | VA | power_in | Power supply input for the 3.3 V to 5.25 V single supply, which also serves as the ADC reference voltage; VA must be set greater than or equal to the maximum VIN signal to avoid saturating the maximum conversion code. |
| 2 | GND | power_in | Analog input signal ground; all analog and digital signals are referenced to this pin. |
| 3 | VIN | power_in | Analog signal input with a range of 0 V to VA. |
| 4 | SCLK | input | Serial clock input that directly controls the conversion and readout process. |
| 5 | SDATA | output | Serial data output; it enters tri-state after the 16th falling edge of SCLK, which ends the conversion cycle. |
| 6 | CS | input | Active-low chip select; a falling edge starts a conversion cycle and the device wakes from auto power-down, and pulling CS high before 10 SCLK cycles aborts the conversion. |
