DAC08Q

Digital To Analog Converters Overview

The DAC08Q is an 8-bit, high-speed multiplying digital-to-analog converter manufactured by Analog Devices Inc. It features a settling time of 85 ns and operates within a temperature range of -55°C to +125°C. The device accepts parallel digital inputs and provides complementary current outputs with a full-scale current prematched to ±1 LSB. It supports a wide power supply range from ±4.5 V to ±18 V and consumes 33 mW at ±5 V supplies. The DAC08Q interfaces directly with TTL, CMOS, ECL, HTL, and PMOS logic families.

Digital To Analog Converters Procurement Notes

Verify the specific grade suffix (e.g., Q for military/aerospace) against the latest Analog Devices ordering guide. Confirm that the component meets MIL-STD-883, Level B requirements if applicable. Check for availability as the DAC08 series may be discontinued or subject to change without notice.

Digital To Analog Converters Selection Notes

Select the DAC08Q for applications requiring high speed and low cost in harsh environments. Ensure the reference resistor temperature coefficient matches the output resistor to minimize full-scale drift. Verify that the logic threshold control pin (VLC) is properly biased for the target logic family to ensure noise immunity.

Digital To Analog Converters Part Context

The DAC08Q belongs to the DAC08 series of monolithic 8-bit D/A converters. This series is designed for high-speed performance with low glitch energy. The 'Q' suffix typically denotes a version processed to MIL-STD-883 standards for military and aerospace use, offering extended temperature ranges compared to commercial variants.

Digital To Analog Converters Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consider evaluating other members of the DAC08 family or newer Analog Devices DAC products for direct replacement, ensuring compatibility with existing logic levels and power supply constraints.

Digital To Analog Converters FAQ

What is the logic input swing range for the DAC08Q?

The logic inputs can swing between -10 V and +18 V when powered from ±15 V supplies, allowing direct interface with 15 V CMOS logic.

How is the logic threshold adjusted?

The logic threshold is adjustable via Pin 1 (VLC). For TTL interface, ground Pin 1. The threshold voltage nominally tracks VLC plus 1.4 V.

What is the maximum reference current?

The recommended operating range for the reference current is 0.2 mA to 4.0 mA, with a maximum absolute rating of 5.0 mA.
