Pin Description

V

IN

This is the analog input. The input range is

GND–50 mV

≤ V

INPUT ≤ V

+ +50mV.

DB0–DB7

TRI-STATE data outputs — bit 0 (LSB)

through bit 7 (MSB).

WR /RDY

WR-RD Mode (Logic high applied to

MODE pin)

WR: With CS low, the conversion is

started on the rising edge of WR. The digi-

tal result will be strobed into the output

latch at the end of conversion (

Figures 2,

3, 4).

RD Mode (Logic low applied to MODE

pin)

RDY: This is an open drain output (no in-

ternal pull-up device). RDY will go low af-

ter the falling edge of CS and returns high

at the end of conversion.

MODE

Mode: Mode (RD or WR-RD ) selection

input– This pin is pulled to a logic low

through an internal 50 µA current sink

when left unconnected.

RD Mode is selected if the MODE pin is

left unconnected or externally forced low.

A complete conversion is accomplished by

pulling RD low until output data appears.

WR-RD Mode is selected when a high is

applied to the MODE pin. A conversion

starts with the WR signal’s rising edge and

then using RD to access the data.

RD

WR-RD Mode (logic high on the MODE

pin)

This is the active low Read input. With a

logic low applied to the CS pin, the

TRI-STATE data outputs (DB0–DB7) will

be activated when RD goes low (

Figures

2, 3, 4).

RD Mode (logic low on the MODE pin)

With CS low, a conversion starts on the

falling edge of RD. Output data appears

on DB0–DB7 at the end of conversion

(

Figures 1, 5).

INT

This is an active low output that indicates

that a conversion is complete and the data

is in the output latch. INT is reset by the

rising edge of RD.

GND

This is the power supply ground pin. The

ground pin should be connected to a

“clean” ground reference point.

V

REF−,VREF+

These are the reference voltage inputs.

They may be placed at any voltage be-

tween GND − 50 mV and V

+ +50mV, but

V

REF+ must be greater than VREF−. Ideally,

an input voltage equal to V

REF− produces

an output code of 0, and an input voltage

greater than V

REF+ − 1.5 LSB produces an

output code of 255.

For the ADC08161 an input voltage that

exceeds V

+ by more than 100 mV or is be-

low GND by more than 100 mV will create

conversion errors.

CS

This is the active low Chip Select input. A

logic low signal applied to this input pin en-

ables the RD and WR inputs. Internally,

the CS signal is ORed with RD and WR

signals.

OFL

Overflow Output. If the analog input is

higher than V

REF+, OFL will be low at the

end of conversion. It can be used when

cascading two ADC08161s to achieve

higher resolution (9 bits). This output is al-

ways

active

and

does

not

go

into

TRI-STATE as DB0–DB7 do. When OFL

is set, all data outputs remain high when

the ADC08061’s output data is read.

V

+

Positive power supply voltage input. Nomi-

nal operating supply voltage is +5V. The

supply pin should be bypassed with a

10 µF bead tantalum in parallel with a 0.1

ceramic capacitor. Lead length should be

as short as possible.

V

REFOUT

The internal bandgap reference’s 2.5V

output is available on this pin. Use a

220 µF bypass capacitor between this pin

and analog ground.
