BU3616K
The BU3616K, a CMOS IC, is a high-speed, low-power-consumption 3-channel 8-bit D / A converter. Its internal ref-
erence voltage source eliminates the need for an external reference voltage source.
•^Applications
Video CDs, CD-V, CD karaoke
•^Features
1) 8-bit resolution.
2) Current output.
3) Low power consumption (typically 75mW).
4) High-speed operation.
5) Internal reference voltage circuit.
6) TTL input.
