Pin Descriptions

DV_CC

AV_CC

These are the digital and analog positive sup-

ply voltage inputs. They should always be con-

nected to the same voltage source, but are

brought out separately to allow for separate

bypass capacitors. Each supply pin should be

bypassed with a 0.1 µF ceramic capacitor in

parallel with a 10 µF tantalum capacitor to

ground.

_IN0, V_IN1

These are the analog input pins. The

ADC10662 has two inputs (V_IN0and V_IN1) and

_IN2, V_IN3

the ADC10664 has four inputs (V_IN0, V_IN1

V_IN2and V_IN3). The impedance of the source

should be less than 500Ω for best accuracy

and conversion speed. For accurate conver-

sions, no input pin (even one that is not se-

lected) should be driven more than 50 mV

above V_CCor 50 mV below ground.

INT

S /H

This is the active low interrupt output. INT

goes low at the end of each conversion, and

returns to a high state following the rising edge

of RD .

GND, AGND, These are the power supply ground pins. The

DGND

ADC10662 and ADC10664 have separate

analog and digital ground pins (AGND and

DGND) for separate bypassing of the analog

and digital supplies. The ground pins should

be connected to a stable, noise-free system

ground. Both pins should be returned to the

same potential.

This is the Sample/Hold control input. When

this pin is forced low (and CS is low), it causes

the analog input signal to be sampled and ini-

tiates a new conversion.

This is the active low Read control input.

When this RD and CS are low, any data

present in the output registers will be placed

on the data bus.

DB0–DB9

These are the TRI-STATE output pins.

SPEED

ADJ

By connecting a resistor between this pin and

ground, the conversion time can be reduced.

The specifications listed in the table of Electri-

cal Characteristics apply for a speed adjust re-

sistor (R_SA) equal to 14.0 kΩ (Mode 1) or 8.26

kΩ (Mode 2). See the Typical Performance

Curves and the table of Electrical Characteris-

tics.

This is the active low Chip Select control input.

When low, this pin enables the RD and S /H

pins.

S0, S1

These pins select the analog input that will be

connected to the A/D during the conversion.

The input is selected based on the state of S0

and S1 when S /H makes its High-to-Low tran-

sition (See the Timing Diagrams). The

ADC10664 includes both S0 and S1. The

ADC10662 includes just S0.

V_REF−

V_REF+

These are the reference voltage inputs. They

may be placed at any voltage between GND

and V_CC, but V_REF+must be greater than

_REF−. An input voltage equal to V_REF−pro-

duces an output code of 0, and an input volt-

age equal to (V_REF+− 1 LSB) produces an out-

put code of 1023.
