Symbol

Description

ANALOG I/O

4-7

IN1 to IN4

Analog inputs. These signals can range from 0V to V

DIGITAL I/O

10

SCLK

Digital clock input. This clock directly controls the conversion

and readout processes.

9

DOUT

Digital data output. The output samples are clocked out of this

pin on falling edges of the SCLK pin.

8

DIN

Digital data input. The ADC104S101’s Control Register is

loaded through this pin on rising edges of the SCLK pin.

1CS

Chip select. On the falling edge of CS, a conversion process

begins. Conversions continue as long as CS is held low.

POWER SUPPLY

2V

A

Positive supply pin. This pin should be connected to a quiet

+2.7V to +5.25V source and bypassed to GND witha1µF

capacitor and a 0.1 µF monolithic capacitor located within 1

cm of the power pin.

3

GND

The ground return for the analog supply and signals.
