16-bit stereo D / A converter
for audio applications
BU9480F
The BU9480F is a 16-bit stereo D / A converter designed for audio applications, and has an internal 2 × oversam-
pling circuit.
•Applications
16-bit stereo D / A converter for audio applications
•Features
1) 3.0 to 5.5V operating voltage.
2) Low current consumption because of the CMOS
process.
3) Resistor strings method used.
•Block diagram
4) 2-channel common phase output.
5) Internal 2 × oversampling interpolator.
6) 8 - pin plastic package.
7) Supports 4fs. (200kHz operation)
