ADS574

Microprocessor-Compatible Sampling

CMOS ANALOG-TO-DIGITAL CONVERTER

FEATURES

DESCRIPTION

● REPLACES ADC574 FOR NEW DESIGNS

The ADS574 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 models in most applications, with internal

sampling, much lower power consumption, and capa-

bility to operate from a single +5V supply.

● COMPLETE SAMPLING A/D WITH

REFERENCE, CLOCK AND

MICROPROCESSOR INTERFACE

● FAST ACQUISITION AND CONVERSION:

25µs max

● ELIMINATES EXTERNAL SAMPLE/HOLD

The ADS574 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

for 12-bit conversions is 25µs over the full operating

temperature range, including both acquisition and con-

version.

IN MOST APPLICATIONS

● GUARANTEED AC AND DC PERFORMANCE

● SINGLE +5V SUPPLY OPERATION

● LOW POWER: 100mW max

● PACKAGE OPTIONS: 0.6" and 0.3" DIPs,

SOIC

Complete user control over the internal sampling func-

tion facilitates elimination of external sample/hold

amplifiers in most existing designs.

The ADS574 requires +5V, with –12V or –15V op-

tional, depending on usage. No +15V supply is re-

quired. Available packages include 0.3" or 0.6" wide

28-pin plastic DIPs and 28-lead SOICs.
