Pin Descriptions and Equivalent Circuits

Pin No.

Symbol

Description

ANALOG I/O

5,4

IN1 and IN2

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

DIGITAL I/O

SCLK

Digital clock input. This clock directly controls the conversion

and readout processes.

DOUT

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

pin on falling edges of the SCLK pin.

DIN

Digital data input. The ADC082S021’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

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.

GND

The ground return for the analog supply and signals.
