Product Summary
The Fujitsu MB88346PF-G-BND-EF is an R-2R type 8-bit resolution digital-to-analog converter (DAC), designed for interface with a wide range of general 4-bit and 8-bit microcontrollers including Fujitsu MB88200 family, MB8850 family, and MB88500 family 4-bit single-chip microcontrollers. The MB88346PF-G-BND-EF has an 8-bit x 12-channel D/A converter with operational amplifier output buffers. Digital data are input serially by individual channel units. The loaded digital data are converted into analog DC voltages by the D/A converter in 20 ms settling time. Also, the MB88346PF-G-BND-EF has operational amplifier output buffers. These operational amplifier output buffers are connected to each channel of the D/A converter, and provide high current drive capability. The MB88346PF-G-BND-EF is suitable for electronic volumes and replacement for potentiometers for adjustment, in addition to normal D/A converter applications.
