Descriptions
The DIO32276 is a high-performance, double-pole
double-throw (DPDT) analog switch with negative
VCC swing audio capability. The DIO32276 is
featured in ultra-low audio RON of 0.8 Ω (typical) at
3.3 V . The DIO32276 operates over a VCC range of
1.65 to 5.5 V, and it is made of sub-micron CMOS
technology to achieve fast switching speeds,
aiming at break-before-make operation. When it is
operating, the turn-on ramp time is selectable by
using an external capacitor (C_EXT) to minimize
pop and click during operation.
The DIO32276 is advantaged in THD+N
specifications which target a Hi-Fidelity audio
quality into both 32 Ω headphones and line out
type loads ( > 600 Ω).
