SNAS298G August 2005 – January 2015 ADC128S102
PRODUCTION DATA.
PIN | I/O | DESCRIPTION | |
---|---|---|---|
NO. | NAME | ||
3 | AGND | Supply | The ground return for the analog supply and signals. |
1 | CS | IN | Chip select. On the falling edge of CS, a conversion process begins. Conversions continue as long as CS is held low. |
12 | DGND | Supply | The ground return for the digital supply and signals. |
14 | DIN | IN | Digital data input. The ADC128S102's Control Register is loaded through this pin on rising edges of the SCLK pin. |
15 | DOUT | OUT | Digital data output. The output samples are clocked out of this pin on the falling edges of the SCLK pin. |
4 - 11 | IN0 to IN7 | IN | Analog inputs. These signals can range from 0 V to VREF. |
16 | SCLK | IN | Digital clock input. The ensured performance range of frequencies for this input is 8 MHz to 16 MHz. This clock directly controls the conversion and readout processes. |
2 | VA | Supply | Positive analog supply pin. This voltage is also used as the reference voltage. This pin should be connected to a quiet +2.7-V to +5.25-V source and bypassed to GND with 1-µF and 0.1-µF monolithic ceramic capacitors located within 1 cm of the power pin. |
13 | VD | Supply | Positive digital supply pin. This pin should be connected to a +2.7 V to VA supply, and bypassed to GND with a 0.1-µF monolithic ceramic capacitor located within 1 cm of the power pin. |
