AD8522ANZ

Overview

The AD8522ANZ is a dual 12-bit, single-supply voltage output digital-to-analog converter (DAC) housed in a 14-pin plastic DIP package. It operates on a +5 V supply and features a serial digital interface with onboard reference and buffered voltage outputs. The device provides a full-scale output of 4.095 V with 1 mV/LSB resolution. Key electrical parameters include a typical settling time of 16 μs to ±1 LSB, relative accuracy of ±1.5 LSB, and power dissipation as low as 5 mW per DAC channel.

Feature Summary

• Dual 12-bit DACs with 4.095 V full-scale output and 1 mV/LSB resolution
• Integrated 2.5 V bandgap reference with external buffer capability
• Rail-to-rail buffered voltage outputs capable of driving ±5 mA
• Serial interface supporting hardware-load and software-load modes

Applications

• Digitally controlled calibration systems
• Servo control loops
• Process control equipment
• Portable instrumentation
• Cellular base station voltage adjustment

Procurement Notes

Verify the package type matches the required application, as the AD8522 family includes both PDIP-14 and SOIC-14 variants. Confirm that the specific ordering suffix corresponds to the desired thermal and mechanical specifications. Ensure compatibility with +5 V single-supply logic levels for the serial interface inputs.

Selection Notes

Select this component for applications requiring low power consumption and minimal external components. The device is optimized for +5 V systems. Consider the 16 μs settling time and 13 nV·s glitch impulse when designing for high-speed or precision signal generation requirements.

Part Context

The AD8522ANZ belongs to the Analog Devices AD8522 series of complete dual 12-bit DACs. It utilizes a CBCMOS process to combine low-power CMOS logic with complementary bipolar analog performance. The 'AN' suffix denotes the 14-pin Plastic DIP package variant within this product line.
