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.

Notes: 1. Preventing Switching Noise To prevent switching noise in the analog output signal, connect noise limiting capacitors to the VCCA and VCCD pins as close to the A.GND and D.GND pins as possible. Power Pattern To reduce parasitic impedance, the PC board pattem to the VCCA, VCCD, A.GND and D.GND pins should be as wide as possible.
