General Description

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.

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.
