BU2505FV
BU2505FV is a high-performance 10bit D/A converter IC that incorporates 10-channel of a R-2R system.
Each channel output incorporates a Rail-to Rail output 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.
REVERSE pin can change the LSB/MSB of 10bit data. Small package (0.65mm pitch and 20pin) is adopted.
Applications
DVD, CD-R, CD-RW, DVC, Digital camera, and other industrial equipments
Features
1) High-performance 10bit D/A converter that incorporates 10-channel of a R-2R system.
2) RESET pin can keep output voltage of all channels within the lower reference voltage range.
3) Digital input compatible with TTL levels.
4) 14bit 3wire serial data + RESET signal input, and cascade connection is possible. LSB first / MSB first of 10bit data
can be changed by REVERSE pin.
