Symbol

Description

ANALOG I/O

3V

IN

Analog input. This signal can range from 0V to V

DIGITAL I/O

4

SCLK

Digital clock input. The range of frequencies for this input is 10 kHz to 20 MHz, with

guaranteed performance at 20 MHz. This clock directly controls the conversion and readout

processes.

5

SDATA

Digital data output. The output words are clocked out of this pin by the SCLK pin.

6CS

Chip select. A conversion process begins on the falling edge of CS.

POWER SUPPLY

1V

DD

Positive supply pin. These pins should be connected to a quiet +2.7V to +5.25V source and

bypassed to GND with 0.1 µF and 1 µF monolithic capacitors located within 1 cm of the

power pin. The ADCS7476/77/78 uses this power supply as a reference, so it should be

thoroughly bypassed.

2

GND

The ground return for the supply.
