Product Summary

The AD7572BQ05 is a complete, 12-bit ADC that offers high speed performance combined with low, CMOS power levels. The AD7572BQ05 uses an accurate, high speed DAC and comparator in a successive-approximation loop to achive 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 the specified accuracy is achieved without any user trims. The AD7572BQ05 is fabricated in Analog Devices linear compatible CMOS process.
