DAC0800LCN

Digital To Analog Converters Overview

The DAC0800LCN is an obsolete monolithic 8-bit high-speed current-output digital-to-analog converter manufactured by Texas Instruments. It features a typical settling time of 100 ns and operates with a wide power supply range from ±4.5V to ±18V. The device provides complementary current outputs, enabling differential output voltages up to 20 Vp-p. It consumes 33 mW at ±5V supplies and interfaces directly with TTL, CMOS, PMOS, and other logic families.

Digital To Analog Converters Feature Summary

• Fast settling output current for high-speed applications
• Wide power supply range supporting diverse system architectures
• Complementary current outputs for differential voltage generation
• Direct interface compatibility with standard logic families

Digital To Analog Converters Applications

• High-speed digital-to-analog conversion systems
• Multiplying DAC configurations requiring monotonic performance
• Differential output signal generation using simple resistor loads

Digital To Analog Converters Procurement Notes

Verify the obsolete status of this component before design integration. Confirm availability through lifetime-buy programs or authorized distributors if existing stock is required. Ensure that alternative sourcing channels are established to mitigate supply chain risks associated with discontinued semiconductor products.

Digital To Analog Converters Selection Notes

Evaluate the need for 8-bit resolution and 100 ns settling speed against modern alternatives. Consider the requirement for current-output architecture and external op-amp buffering. Assess whether the wide supply range and direct logic interfacing capabilities justify the use of this legacy component over newer integrated solutions.

Digital To Analog Converters Part Context

This device belongs to the DAC0800 series, which serves as a direct replacement for the DAC-08, DAC-08A, DAC-08C, and DAC-08H. It is designed for applications requiring high-speed conversion and low power consumption. The series supports both unipolar and bipolar operation modes with appropriate external circuitry.

Digital To Analog Converters Replacement Considerations

The DAC0800LCN is officially listed as obsolete. Designers should consider the DAC0800LCMX/NOPB (SOIC package) or the DAC0800LCM/NOPB as potential pin-compatible or functionally equivalent replacements within the same product family.
