MAX174/MX574A/

MX674A

Industry-Standard, Complete 12-Bit ADCs

General Description

Features

The MAX174/MX574A/MX674A are complete 12-bit

analog-to-digital converters (ADCs) that combine high

speed, low-power consumption, and on-chip clock and

voltage reference. The maximum conversion times are

8μs (MAX174), 15μs (MX674A), and 25μs (MX574A).

Maxim’s BiCMOS construction reduces power dissipation

3 times (150mW) over comparable devices. The internal

buried zener reference provides low-drift and low-noise

performance. External component requirements are lim-

ited to only decoupling capacitors and fixed resistors. The

versatile analog input structure allows for 0 to +10V or 0

to +20V unipolar or ±5V or ±10V bipolar input ranges with

pin strapping.

● Complete ADC with Reference and Clock

● 12-Bit Resolution and Linearity

● No Missing Codes Over Temperature

● 150mW Power Dissipation

● 8μs (MAX174), 15μs (MX674A), and 25μs (MX574A)

Max Conversion Times

● Precision Low TC Reference: 10ppm/°C

● Monolithic BiCMOS Construction

● 150ns Maximum Data Access Time

Applications

The MAX174/MX574A/MX674A use standard micropro-

cessor interface architectures and can be interfaced to 8-,

12-, and 16-bit wide buses. Three-state data outputs are

controlled by CS, CE, and R/C logic inputs.

● Digital Signal Processing

● High-Accuracy Process Control

● High-Speed Data Acquisition

● Electro-Mechanical Systems
