DESCRIPTION
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 4-
bit 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 chan-
nel units. The loaded digital data are converted into analog DC voltages
by the D/A converter in 20
μ
s settling time. Also, the MB88346B 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 MB88346B is suitable for electronic
volumes and replacement for potentiometers for adjustment, in addition
to normal D/A converter applications.
