Overview
The AD8300ANZ 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 operates on a supply voltage range of +2.7 V to +5.5 V and includes a double-buffered serial interface compatible with DSPs and microcontrollers. Key electrical parameters include a maximum settling time of 6 ms at +5 V, a power dissipation of 3.6 mW at +3 V, and an operating temperature range from –40 °C to +85 °C.
Feature Summary
- Complete 12-bit DAC with no external components required
- Single +3 V operation with 2.0475 V full-scale output
- Double-buffered 3-wire serial interface (SDI, CLK, LD)
- Internal curvature-corrected bandgap reference
Applications
- Portable communications systems
- Digitally controlled calibration circuits
- Servo controls
- PC peripherals
Procurement Notes
Verify the package type matches the 'AN' suffix designation as plastic DIP (N-8). Confirm that the specific revision of the datasheet aligns with the manufacturing date code. Ensure ESD precautions are observed during handling due to the sensitivity of the CMOS input structures.
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 5 mA sourcing current capability meets load requirements and that the serial interface timing constraints fit the host controller's clock speeds.
Part Context
The AD8300ANZ belongs to the AD8300 series of monolithic DACs manufactured by Analog Devices using CBCMOS process technology. The 'AN' suffix specifically identifies the 8-Lead Plastic DIP package variant, distinguishing it from the surface-mount SO-8 option (AD8300AR). This family is optimized for cost-effective integration in single-supply environments.
Replacement Considerations
The AD8300AR serves as the surface-mount equivalent within the same product line. No other direct pin-compatible replacements are documented in the provided source material.
