AD7247AANZ

The AD7247AANZ is a dual 12-bit voltage output digital-to-analog converter (DAC) manufactured by Analog Devices Inc. This device integrates two complete 12-bit CMOS DACs with on-chip voltage reference, output amplifiers, and reference buffer amplifiers on a single monolithic chip. It operates from a single 10.8V to 16.5V supply or dual supplies, with typical power consumption of 165 mW in single supply mode.

Key specifications include a 12-bit resolution, settling time of 8 µs typical, and both external and internal reference options. The R-2R architecture ensures monotonic performance with integral nonlinearity (INL) of ±1 LSB max and differential nonlinearity (DNL) of ±0.9 LSB max. The data interface is parallel, supporting easy integration with microprocessors.

The device is housed in a through-hole 24-DIP (0.300 inch, 7.62mm) package, specifically the 24-PDIP supplier package. It operates over the industrial temperature range of -40°C to +85°C. The output voltage range is 0V to +5V or 0V to +10V with single supply, and ±5V with dual supplies.

This DAC is suitable for applications requiring precision voltage output generation, such as industrial control, instrumentation, and data acquisition systems. The AD7247AANZ variant features parallel loading structure for the interface.
