FUJITSU SEMICONDUCTOR DATA SHEET DS04-13506-3E Linear IC General purpose Converter CMOS 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.
