CA3338E

Digital To Analog Converters Overview

The CA3338E is a CMOS/SOS high-speed digital-to-analog converter manufactured by Harris Corporation. It features an 8-bit resolution and operates at video speeds with a typical update rate of 50 MSPS. The device utilizes an R2R architecture to produce rail-to-rail output swings from a single +5V supply. Internal level shifters allow for output ranges below digital ground, while segmented thermometer encoding of the upper three bits minimizes glitch energy. Key electrical parameters include a typical settling time of 20ns to 1/2 LSB and accuracy of ±0.5 LSB.

Digital To Analog Converters Feature Summary

• CMOS/SOS technology ensures low dynamic power dissipation and inherent latch-up resistance on a sapphire substrate.
• Segmented R2R ladder network design significantly reduces glitch energy during transitions.
• Internal level shifters enable flexible output voltage ranges extending below digital ground.

Digital To Analog Converters Applications

• TV and Video Display systems
• High Speed Oscilloscope Displays
• Digital Waveform Generators
• Direct Digital Synthesis

Digital To Analog Converters Procurement Notes

Verify the manufacturer origin carefully as Harris Corporation's semiconductor assets were acquired by Intersil, which was subsequently acquired by Renesas Electronics. Ensure the specific part number corresponds to the intended legacy or current production source. Confirm RoHS compliance status and package availability through authorized distributors or verified component databases before procurement.

Digital To Analog Converters Selection Notes

Select this component when high-speed video processing requires low power consumption and minimal signal glitches. The CMOS/SOS construction offers advantages in radiation-hardened or high-reliability environments due to its latch-up resistance. Consider the single-supply operation and internal level shifting capabilities if the system design requires output voltages that swing below the digital logic ground reference.

Digital To Analog Converters Part Context

The CA3338 series belongs to a family of high-speed digital-to-analog converters designed for video applications. Originally produced by Harris Semiconductor, these devices are characterized by their use of CMOS-on-Sapphire (CMOS/SOS) technology. This manufacturing process distinguishes them from standard CMOS DACs by providing superior performance in terms of speed, power efficiency, and robustness against latch-up conditions.

Digital To Analog Converters Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. Due to the acquisition history involving Harris, Intersil, and Renesas, cross-reference with Intersil datasheets for potential equivalent specifications. Verify pin compatibility and electrical characteristics with any alternative high-speed 8-bit DACs before implementation.
