D/A Converter for Digital Tuning
(8-channel, 8-bit, on-chip OP amp, low-voltage)
MB88347L
DESCRIPTION
FEATURES
• Ultra-low power consumption (0.5 mW/ch: typical)
• Low voltage operation (V
• Ultra-compact space-saving package (SSOP-16)
• Contains 8-channel R-2R type 8-bit D/A converter
• On-chip analog output amps (sink current max. 1.0 mA, source current max. 1.0 mA)
• Analog output range from 0 V to V
• Two separate power supply/ground lines for MCU interface block/operational amplifier output buffer block and
• Serial data input, maximum operating speed 2.5 MHz
• CMOS process
• Package lineup includes DIP 16-pin, SOP 16-pin, SSOP 16-pin
PACKAGES
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.
