10-BIT D/A CONVERTER
MB40760
■DESCRIPTION
MB40760 is a low-power consum ption, high-speed 10-bi t D/A conve rter.
The MB40760 is cha racterized by TTL comp atible 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 e xternal reference voltage.
The MB40760 D/A conve rter is suitable fo r high-resolution TVs or VTRs.
■FEATURES
• Resolution: 10 bits
• Conversion char acteristics:
Maxim um conversion rate: 60 MHz (Minimum)
Linearity error: ±0.1% (M aximum)

Notes:
1. Preventing Switching Noise
To prevent switching noise in th e an alog out put signal , c onnect noi se li miting c apacitors t o the V CCA and
VCCD pins as close to the A.GND and D.GND pins as possible.
2. Power Pattern
To reduce parasi tic impedance, the PC board pattem to the VCCA, VCCD, A.GND and D.GND pins should
be as wide as possible.
