■ DESCRIPTION

The MB40768H 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 60 MHz. 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 MB40768H is suitable for high-definition TV or VCR application.
