PRODUCTION DATA.
| PIN | TYPE(1) | DESCRIPTION | |
|---|---|---|---|
| NO. | NAME | ||
| 1 | VA | P | Positive supply pin. This pin must be connected to a quiet 2.7-V to 5.25-V source and bypassed to GND with a 1-µF capacitor and a 0.1-µF monolithic capacitor located within 1 cm of the power pin. |
| 2 | GND | G | The ground return for the supply and signals. |
| 3 | VIN | I | Analog input. This signal can range from 0 V to VA. |
| 4 | SCLK | I | Digital clock input. This clock directly controls the conversion and readout processes. |
| 5 | SDATA | O | Digital data output. The output samples are clocked out of this pin on falling edges of the SCLK pin. |
| 6 | CS | I | Chip select. On the falling edge of CS, a conversion process begins. |
| PAD | GND | G | For package suffix CISD(X) only. TI recommends connecting the center pad to ground. |
