Details, datasheet, quote on part number: MX674ALEPI+
PartMX674ALEPI+
CategoryData Conversion => ADC (Analog to Digital Converters) => 10-14 bit => 12 bit
DescriptionIndustry-Standard, Complete 12-Bit ADCs
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). Maxims 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 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 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 15s (MX674A), and 25s (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 limited to only decoupling capacitors and fixed resistors. The versatile analog input structure allows for to +20V unipolar or 10V bipolar input ranges with pin strapping. The MAX174/MX574A/MX674A use standard microprocessor interface architectures and can be interfaced 8-, 12-, and 16-bit wide buses. Three-state data outputs are controlled by CS, CE, and R/C logic inputs.
