Rochester Electronics Data Acquisition - Digital to Analog Converters (DAC) AD7247AQ

The AD7247A is a dual 12-bit digital-to-analog converter (DAC) designed for applications requiring high precision and reliability. It operates with a supply voltage range of 12 V to 15 V and features a complete on-chip solution that includes output amplifiers and a voltage reference, eliminating the need for external trimming. The device supports both single and dual supply operations, providing output voltage ranges of 0 V to +5 V and 0 V to +10 V for single supply, and additional -5 V range for dual supplies. The AD7247A is microprocessor compatible, featuring a fast interface with a typical data setup time of 30 ns. It accepts 12-bit parallel data and utilizes a loading structure that allows for efficient data transfer. The DAC is fabricated using Linear Compatible CMOS (LC¬=MOS) technology, ensuring low power consumption of approximately 165 mW in single supply mode. With guaranteed monotonicity and low offset errors, the AD7247A is suitable for applications requiring accurate analog output. It is available in both plastic and hermetic dual-in-line packages, making it versatile for various design requirements.
