D/A Converter for Digital Tuning
(8 channels. 8-bit, with OP amplifier)
MB88347
■ DESCRIPTION
The MB88347 features 8 channels of 8-bit D/A converters (with output amplifiers). The output amplifier provides
high current drive capability. As data is input via a serial link, only three control lines are required, and cascaded
connections can be used.
The MB88347 is suitable for electronic volumes and replacement for potentiometers for adjustment, in addition
to normal D/A converter applications.
■ FEATURES
• Low power consumption (2 mW/ch)
• Small package
• Integrating 8 channels of R-2R type 8-bit D/A converter.

(Continued)
• Built-in analog output amplifier (Max +1.0 mA sink/source current)
• Analog output range : 0 to VCC
• The range of D/A conversion can be independently set by separated the power supply for MCU interface and
OP amplifier and the power supply for D/A converter.
• Capable of being controlled directly by a 3-V MCU (input voltage : “H” = 0.5 V CC, “L” = 0.2 V CC)
• Serial data input, 2.5 MHz operation
• CMOS process
• Package lineup : DIP 16-pin, SOP 16-pin, SSOP 16-pin

incorporating safety design measures into your facility and
equipment such as redundancy, fire protection, and prevention of
over-current levels and other abnormal operating conditions.
If any products described in this document represent goods or
technologies subject to certain restrictions on export under the
Foreign Exchange and Foreign Trade Law of Japan, the prior
authorization by Japanese government will be required for export
