FUJITSU SEMICONDUCTOR DATA SHEET DS04-13501-2E LINEAR IC R-2R TYPE 8-BIT D/A CONVERTER WITH OPERATIONAL AMPLIFIER OUTPUT BUFFERS MB88346B s DESCRIPTION MB88346B-P The Fujitsu MB88346B is an R-2R type 8-bit resolution digital-to-analog converter (DAC), designed for interface with a wide range of general 4bit and 8-bit microcontrollers including Fujitsu’s MB88200 family, MB8850 family, and MB88500 family 4-bit single-chip microcontrollers. The MB88346B 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 µs settling time. Also, the MB88346B has operational amplifier output buffers.
