DESCRIPTION

The ADC0816, ADC0817 data acquisition component

•

is a monolithic CMOS device with an 8-bit analog-to-

analog span adjusted voltage reference

digital

converter,16-channel

multiplexer

and

•

16-channel multiplexer with latched control

microprocessor compatible control logic. The 8-bit

logic

A/D converter uses successive approximation as the

Outputs meet TTL voltage level specifications

conversion technique. The converter features a high

impedance chopper stabilized comparator, a 256R

•

0V to 5V analog input voltage range with

voltage divider with analog switch tree and a

single 5V supply

successive approximation register. The 16-channel

•

No zero or full-scale adjust required

multiplexer can directly access any one of 16-single-

•

Standard hermetic or molded 40-pin MDIP

ended analog signals, and provides the logic for

package

additional channel expansion. Signal conditioning of

any analog input signal is eased by direct access to

Temperature range

−40°C to +85°Cor −55°C to

the multiplexer output, and to the input of the 8-bit

+125°C

A/D converter.

•

Latched TRI-STATE output

The device eliminates the need for external zero and

•

Direct access to “comparator in” and

full-scale

adjustments.
