FEATURES

DESCRIPTION

The ADC0801, ADC0802, ADC0803, ADC0804 and

•

Compatible with 8080 µP derivatives – no

ADC0805 are CMOS 8-bit successive approximation

A/D converters that use a differential potentiometric

ladder — similar to the 256R products. These

converters are designed to allow operation with the

NSC800 and INS8080A derivative control bus with

TRI-STATE output latches directly driving the data

bus. These A/Ds appear like memory locations or I/O

ports to the microprocessor and no interfacing logic is

needed.

interfacing logic needed – access time 135 ns

•

Easy interface to all microprocessors, or

operates “stand alone”

•

Differential analog voltage inputs

Logic inputs and outputs meet both MOS and

TTL voltage level specifications

•

Works with 2.5V (LM336) voltage reference

On-chip clock generator

Differential analog voltage inputs allow increasing the

common-mode rejection and offsetting the analog

zero input voltage value. In addition, the voltage

reference input can be adjusted to allow encoding

any smaller analog voltage span to the full 8 bits of

resolution.

0V to 5V analog input voltage range with

single 5V supply

•

No zero adjust required

Operates ratiometrically or with 5 V_DC, 2.5 V_DC

or analog span adjusted voltage reference
