R-2R TYPE 8-BIT D/A CONVERTER WITH
OPERATIONAL AMPLIFIER OUTPUT BUFFERS
MB88347
s DESCRIPTION
The Fujitsu MB88347 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 MB88347 has an 8-bit × 8-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 100 µs settling time. Also, the MB88347 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
MB88347 is suitable for electronic volumes and replacement for potentiometers for adjustment, in addition to normal
D/A converter applications.
s FEATURES
• Conversion method : R-2R resistor ladder
• 8-bit × 8-channel D/A converter with operational amplifier output buffers
• Max. 2.5 MHz Serial data input
