D/A Converter for Digital Tuning
(8-channel, 8-bit, on-chip OP amp, low-voltage)
MB88347L
■ DESCRIPTION
The MB88347L incorporates eight 8-bit D/A converter modules. This device operates at low supply voltage in
the performance guarantee range from 2.7 to 3.6 V. It also contains an output amplifier, allowing driving at large
current.
Since the MB88347L inputs data in serial mode, it requires only three control lines for data input and two or
more MB88347L units can be cascaded.
The MB88347L is function and pin compatible with the MB88347 (5-volt supply voltage model). The MB88347L
can therefore easily replace the MB88347 in a system, thereby reducing the system’s voltage requirement.
The MB88347L is the best replacement for electronic variable resistors or screwdriver control resistors.
