10-BIT D/A CONVERTER
MB40760
s
DESCRIPTION
MB40760 is a low-power consumption, high-speed 10-bit D/A converter.
The MB40760 is characterized by TTL compatible digital inputs, an analog output voltage from 3 to 5V, and a
maximum conversion rate of 60 MHz. It provides a reference voltage from a potential divider and band-gap
reference, and can also use an external reference voltage.
The MB40760 D/A converter is suitable for high-resolution TVs or VTRs.
