■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 seriallink, 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.

• 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 beindependently set by separated the power supply for MCU interface and

OP amplifier and the power supply for D/A converter.

• Capable of being controlled directlyby a 3-V MCU (input voltage : “H” =0.5 VCC, “L” =0.2 VCC)

• Serial data input, 2.5 MHz operation

• CMOS process

• Package lineup : DIP 16-pin, SOP 16-pin, SSOP 16-pin
