10-BIT D/A CONVERTER
MB40730
MB40730 is a low-power consumption, high-speed 10-bit D/A converter.
The MB40730 is characterized by ECL (10 kH) compatible digital inputs, an
analog output voltage from -2 to 0 V, and a maximum conversion rate of 60 MHz.
It provides a ref erence v oltage from a potential divider and band-gap ref erence,
and can also use an external reference voltage.
The MB40730 D/A converter is suitable for high-resolution TVs or VTRs.

This device contains circuitry to protect the inputs
against damage due to high static voltages or electric
fields. However, it is advised that normal precautions
be taken to avoid application of any voltage higher
than maximum rated voltages to this high impedance
circuit.
