Product Summary

The MB40768 is a low-power and high-speed 8-bit D/A converter. The digital input is TTL compatible and the analog output voltage is 3 to 5 V. Maximum conversion speed is 60MHz. The internal reference voltage provided has two types of resistor division scheme and band-gap reference scheme; the external reference voltage may also be used. The MB40768 is suitable for high-definition TV or VCR application.
