AD7572 Datasheet PDF

●The AD7572AJNZ10 is a LC²MOS complete high speed 12-bit Analog-to-digital Converter (ADC) offers high speed performance combined with low, CMOS power levels. The part uses an accurate, high speed DAC and comparator in a successive-approximation loop to achieve a fast conversion time. An on-chip buried Zener diode provides a stable reference voltage to give low drift performance over the full temperature range and specified accuracy is achieved without any user trims. An on-chip clock circuit is provided, which may be use with a crystal for stand-alone operation, which may be driven from an external clock source such as a divided-down microprocessor clock. It has a high speed digital interface with three-state data outputs and can operate under the control of standard microprocessor READ (RD) and diode address (CS) signals. Interface timing is sufficiently fast to allow the converter to operate with most microprocessors.

● Faster conversion time

● Better offset and gain error

● Low power -100mW
