ADS774

Microprocessor-Compatible Sampling

CMOS ANALOG-to-DIGITAL CONVERTER

FEATURES

DESCRIPTION

● REPLACES ADC574, ADC674 AND ADC774

The ADS774 is a 12-bit successive approximation

analog-to-digital converter using an innovative

capacitor array (CDAC) implemented in low-power

CMOS technology. This is a drop-in replacement for

ADC574, ADC674, and ADC774 models in most

applications, with internal sampling, much lower power

consumption, and the ability to operate from a single

+5V supply.

FOR NEW DESIGNS

● COMPLETE SAMPLING A/D WITH

REFERENCE, CLOCK AND

MICROPROCESSOR INTERFACE

● FAST ACQUISITION AND CONVERSION:

8.5µs max OVER TEMPERATURE

● ELIMINATES EXTERNAL SAMPLE/HOLD

The ADS774 is complete with internal clock, micro-

processor interface, three-state outputs, and internal

scaling resistors for input ranges of 0V to +10V, 0V to

+20V, ±5V, or ±10V. The maximum throughput time

is 8.5µs over the full operating temperature range,

including both acquisition and conversion.

IN MOST APPLICATIONS

● GUARANTEED AC AND DC PERFOR-

MANCE

● SINGLE +5V SUPPLY OPERATION

● LOW POWER: 120mW max

Complete user control over the internal sampling func-

tion facilitates elimination of external sample/hold

amplifiers in most existing designs.

● PACKAGE OPTIONS: 0.6" and 0.3" DIPs,

SOIC

The ADS774 requires +5V, with –15V optional. No

+15V supply is required. Available packages include

0.3" or 0.6" wide 28-pin plastic DIP and 28-pin SOICs.
