BU2507FV
BU2507FV is an IC that incorporates 10bit 6-channel D/A converter using the R-2R system. Each channel output
incorporates a Rail to Rail type output with buffer amplifier. This IC utilizes the TTL level input method. RESET pin can
keep the output voltage in the lower reference voltage range.
zApplications
DVD, CD-R, CD-RW, DVC, Digital camera, and other industrial equipments.
zFeatures
1) High-performance 10bit 6-channel D/A converter adopting the R-2R system.
2) Power supply voltage : 4.5~5.5V.
3) Each channel output incorporates a Rail to Rail type output with buffer amplifier.
4) RESET pin can keep output voltage of all channels within the lower reference voltage range.
5) Digital input compatible with TTL levels.
6) 10MHz input frequency.
7) 14bit 3wire serial data + RESET signal input. (4bit address + 10bit data)
