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).
