■ DESCRIPTION

The MB40988 is an 8-bit resolution ultra high-speed digital-to-analog converter, designed for video processing applications.

The MB40988 has 8-bit resolution 3 channel D/A converters. Digital signals are input to the 8-bit digital input ports, and the input digital data are converted to the analog signals in minimum 80 Mega sample per seconds (MSPS).

The analog output voltage is provided in a range of DC +3V to +5V (2Vp-p level) .

The MB40988 is fabricated by the Fujitsu’s advanced bipolar process and housed in a 48-pin plastic QFP.

The MB40988 is designed for video signal processing applications, and it is suitable for TVS and VCRS.
