D/A Converter (1-ch, 8-bit, 60 MSPS)
MB40768H
■ 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.
■ FEATURES
• Resolution: 8 bits
• Conversion characteristics: Maximum conversion rate: 60 MSPS [min.]
Linearity error: ±0.2 % [max.]
• I/O: Digital input voltage: TTL level
Analog output voltage: 2VP-P (3 to 5 V)
• Reference voltage: VROUT1: Resistor division circuit (0.6 × VCCA)
VROUT2: Band-gap reference circuit (VCCA – 2 V)
• Power supply voltage: +5 V single power supply
• Power consumption: 160 mW [typical value for the analog output voltage of 2 VP-P]
120 mW [typical value for the analog output voltage of 1 VP-P]

■ NOTES ON USAGE
• Countermeasures for switching noise
To prevent the switching noise riding on the analog output signal to the maximum possible extent, insert the
noise limiting capacitor between VCCA-A.GND pins, and between VCCD-D.GND pins closest as possible to the
IC pins.
• Power supply patterns
To reduce parasitic impedance, use the patterns as wide as possible to be connected to the VCCA, VCCD, A.GND
and D.GND pins.
