CA3338AE

Digital To Analog Converters Overview

The CA3338AE is an 8-bit CMOS/SOS high-speed digital-to-analog converter manufactured on a sapphire substrate. It operates from a single +5V supply and delivers rail-to-rail output swings with low dynamic power dissipation. The device features a modified R2R ladder network segmented for the upper three bits to minimize glitch energy. It supports unipolar or bipolar operation via internal level shifters and optional negative supplies. Key electrical specifications include a typical update rate of 50MHz, settling time to 1/2 LSB of 20ns, and accuracy of ±0.75 LSB integral linearity error.

Digital To Analog Converters Feature Summary

• CMOS/SOS technology provides inherent latch-up resistance and low output capacitance.
• Segmented R2R architecture with thermometer encoding reduces glitch energy significantly.
• TTL and CMOS compatible inputs allow direct interfacing with standard logic families.
• Data complement control enables input data inversion without external circuitry.

Digital To Analog Converters Applications

• TV and video display systems
• High-speed oscilloscope displays
• Digital waveform generators
• Direct digital synthesis circuits

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to obsolescence. Confirm package type and suffix requirements against current inventory availability. Ensure handling procedures comply with electrostatic discharge standards for CMOS devices. Review datasheet revisions for any updates to pin configurations or electrical characteristics prior to final procurement.

Digital To Analog Converters Selection Notes

Select the CA3338AE when specific accuracy requirements demand ±0.75 LSB integral linearity compared to the standard CA3338E variant. Consider the sapphire substrate construction for applications requiring lower power dissipation and higher speed stability. Evaluate bipolar operation needs if output ranges below ground are necessary using the VEE pin.
