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
8s (MAX174), 15s (MX674A), and 25s (MX574A).
Maxim’s BiCMOS construction reduces power dissipa-
tion 3 times (150mW) over comparable devices. The
internal buried zener reference provides low-drift and
low-noise performance. External component require-
ments are limited 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.
