AD8300ARZ-REEL

Overview

The AD8300ARZ-REEL is a complete 12-bit digital-to-analog converter (DAC) designed for single +3 V operation. It features a laser-trimmed internal reference providing a 2.0475 V full-scale output with 0.5 mV per bit resolution. The device utilizes a CBCMOS process and includes a rail-to-rail output amplifier capable of sourcing 5 mA and sinking 2 mA. It operates on a supply voltage range of +2.7 V to +5.5 V, consuming as little as 3.6 mW at +3 V. The component uses a double-buffered serial interface compatible with DSPs and microcontrollers, housed in an 8-lead SOIC package.

Feature Summary

• Complete 12-bit DAC with no external components required
• Single +3 V operation with +2.7 V to +5.5 V supply range
• Laser-trimmed 2.0475 V full-scale output (0.5 mV/LSB)
• Double-buffered serial interface (SDI, CLK, LD, CS)

Applications

• Portable communications systems
• Digitally controlled calibration circuits
• Servo controls
• PC peripherals

Procurement Notes

Verify the REEL suffix indicates tape and reel packaging. Confirm the ARZ designation corresponds to the 8-lead SOIC package and RoHS compliance. Ensure the operating temperature range matches the industrial specification of –40 °C to +85 °C. Check datasheet revisions for any updates to absolute maximum ratings or timing parameters before finalizing procurement specifications.

Selection Notes

Select this component when a low-power, single-supply DAC is required for battery-operated applications. The 12-bit resolution and 0.5 mV/LSB step size suit precision control tasks. Verify that the load requirements do not exceed the 5 mA source or 2 mA sink capabilities. Consider the 6 ms settling time for system speed constraints. Ensure logic levels from the driving controller are compatible with the specified input thresholds.

Part Context

The AD8300 is part of Analog Devices' family of complete, ready-to-use DACs. It integrates a bandgap reference, R-2R ladder, and output amplifier into a monolithic CBCMOS circuit. The ARZ-REEL variant specifically denotes the surface-mount SOIC package configuration supplied in reels for automated assembly processes.
