AD8300AR

Overview

The AD8300AR is a complete 12-bit digital-to-analog converter (DAC) designed for single-supply 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 operates within a supply voltage range of +2.7 V to +5.5 V. Key electrical parameters include a typical settling time of 6 ms at +5 V, a maximum power dissipation of 5.1 mW, and an output capable of sourcing 5 mA. It employs a double-buffered three-wire serial interface compatible with DSPs and microcontrollers.

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
Double-buffered 3-wire serial interface (SDI, CLK, LD)
Laser-trimmed 2.0475 V full-scale output

Applications

Portable communications systems
Digitally controlled calibration circuits
Servo controls
PC peripherals

Procurement Notes

Verify the package type matches the 'AR' suffix, which indicates an 8-lead SOIC surface-mount package. Confirm the temperature grade corresponds to the industrial range (-40°C to +85°C). Ensure logic levels from the driving controller are compatible with the specified input thresholds for the selected supply voltage.

Selection Notes

Select this component when a low-cost, single-supply DAC is required for battery-operated applications. The AD8300AR is suitable for designs needing a rail-to-rail output amplifier with up to 5 mA source current. Consider the 6 ms settling time for speed requirements and verify that the 3-wire interface aligns with the system's control bus architecture.

Part Context

The AD8300 series includes both plastic DIP (AN suffix) and SOIC (AR suffix) packages. Both variants share identical electrical specifications and functionality. The AR variant specifically denotes the 8-lead Small Outline Integrated Circuit (SO-8) package with a height of 1.5 mm, designed for surface-mount assembly.
