BU2501FV

Optical disc ICs BU2500FV / BU2501FV 8bit 12-channel D/A converter BU2500FV / BU2501FV BU2500FV / BU2501FV is a 12ch high-performance 8bit D/A converter which adopts the R-2R system. The BU2500FV utilizes a 5V supply voltage and the BU2501FV a 3V. Each channel output incorporates a Rail to Rail output type buffer amplifier. Three wire serial data input and cascade connection is possible. Small package (0.65mm pitch and 20pin) is adopted. zApplications CD-R, CD-RW, DVC, Digital camera and industrial equipment zFeatures 1) High-performance 8bit 12-channel D/A converter adopting the R-2R system. 2) Output of each channel incorporates a Rail to Rail output type buffer amplifier. 3) Digital input compatible with TTL levels. 4) 12bit 3wire serial data input, cascade connection is possible. 5) Buffer amplifier of each channel is highly-stable. Prevents oscillation even with capacitance loads. zAbsolute maximum ratings (Ta=25°C) Parameter Symbol Limits Supply voltage Upper reference voltage of D/A converter Input voltage Output voltage Power dissipation VCC VDD VIN VOUT Pd −0.3~+6.0 −0.3~+6.0 −0.3~+6.0 −0.3~+6.0 400∗ Operating temperature Topr −25~+85 Storage temperature Tstg −55~+125 ∗ Reduced by 4mW for each increase in Ta of 1°C over 25°C.
