AD7524SD

The Analog Devices AD7524SD is a 12-bit CMOS multiplying digital-to-analog converter (DAC). It is designed for direct interface to 4- or 8-bit microprocessors. The component features parallel word input loading, supporting both binary and offset binary input formats, making it suitable for interfacing with microcontrollers or DSPs.

Key specifications include a 12-bit resolution, a maximum linearity error of 0.0244%, and a typical gain drift of 2ppm/°C. It operates with a nominal supply voltage of 5V and has a maximum power dissipation of 40mW. The DAC offers a fast interface timing with a maximum settling time of 2µs.

Housed in a hermetic sealed, side brazed ceramic DIP-16 package, the AD7524SD is suitable for industrial control, data acquisition, and instrumentation applications. It operates over a temperature range of -25°C to +85°C, ensuring reliability in various environments.

The device features a clear input for resetting the DAC register to zeros during power-up. Data loading operations are similar to the WRITE cycle of a static RAM, with data loaded in three 4-bit bytes into data registers before being transferred to the 12-bit DAC register.
