19-2765 Rev 3 8/11 EVALUATION KIT AVAILABLE MAX174/MX574A/MX674A Industry-Standard, Complete 12-Bit ADCs General Description Features The MAX174/MX574A/MX674A are complete 12-bit S Complete ADC with Reference and Clock analog-to-digital converters (ADCs) that combine high S 12-Bit Resolution and Linearity speed, low-power consumption, and on-chip clock and voltage reference. The maximum conversion times are S No Missing Codes Over Temperature 8s (MAX174), 15s (MX674A), and 25s (MX574A). S 150mW Power Dissipation Maxims BiCMOS construction reduces power dissipa- S 8s (MAX174), 15s (MX674A), and 25s (MX574A) tion 3 times (150mW) over comparable devices. The internal buried zener reference provides low-drift and Max Conversion Times low-noise performance. External component require- S Precision Low TC Reference: 10ppm/NC ments are limited to only decoupling capacitors and fixed S Monolithic BiCMOS Construction resistors. The versatile analog input structure allows for 0 to +10V or 0 to +20V unipolar or 5V or 10V bipolar S 150ns Maximum Data Access Time input ranges with pin strapping. Applications The MAX174/MX574A/MX674A use standard micropro- cessor interface architectures and can be interfaced to Digital Signal Processing 8-, 12-, and 16-bit wide buses. Three-state data outputs High-Accuracy Process Control are controlled by CS, CE, and R/C logic inputs. High-Speed Data Acquisition Ordering Information appears at end of data sheet.

Indefinite short to V or AGND CC Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, and functional opera- tion of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
