D/A Converter for Digital Tuning
(12 channels. 8-bit, with OP amplifier)
MB88346B
DESCRIPTION
The MB88346B features 12 channels of 8-bit D/A converters with output amplifier for digital tuning. The output
amplifier provides high current drive capability.
As the MB88346B inputs data in serial, it requires only three control lines and can also be cascade-connected
with the MB88340 series.
The MB88346B is suitable for electronic volumes and replacement for potentiometers for adjustment, in addition
to normal D/A converter applications.
FEATURES
• Low power consumption
• Small package
• Integrating 12 channels of R-2R type 8-bit D/A converter
PACKAGES
