SNAS279F April 2005 – July 2016 ADC084S021
PRODUCTION DATA.
PIN | I/O | DESCRIPTION | |
---|---|---|---|
NO. | NAME | ||
1 | CS | I | Chip select. A conversion begins at the falling edge of CS. Conversions continue as long as CS is held low. |
2 | VA | — | Positive supply pin. This pin must be connected to a quiet 2.7-V to 5.25-V source and be bypassed to GND with a 0.1-µF monolithic capacitor located within 1 cm of the power pin and with a 1-µF capacitor. |
3 | GND | — | Device ground return for all signals. |
4, 5, 6, 7 | IN1 to IN4 | I | Analog inputs. These signals can range from 0 V to VA. |
8 | DIN | I | Digital data input. The ADC084S021's control register is loaded through this pin on rising edges of SCLK. |
9 | DOUT | O | Digital data output. The output samples are clocked out at this pin on falling edges of the SCLK pin. |
10 | SCLK | I | Digital clock input. This clock directly controls the conversion and readout processes. |
