MAX174/MX574A/MX674A
Industry-Standard, Complete 12-Bit ADCs
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 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.

隋心安心 51mcu
Multisim simulates the switching power supply. The maximum output voltage is sufficient, but the maximum output current is not enough. What should I do?
1. When the maximum output voltage reaches the required value, the current keeps changing between 500mA and 501mA. The maximum output current should be 3A. What is the reason? 2. Why does the noise ri...
