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 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.  
S Complete ADC with Reference and Clock  
S 12-Bit Resolution and Linearity  
S No Missing Codes Over Temperature  
S 150mW Power Dissipation  
S 8µs (MAX174), 15µs (MX674A), and 25µs (MX574A)  
Max Conversion Times  
S Precision Low TC Reference: 10ppm/NC  
S Monolithic BiCMOS Construction  
S 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.
