DIO32276

DPDT (0.8 Ω) HiFi Audio Switch with Negative Swing

Features

Descriptions



Power supply voltage range: 1.65 to 5.5 V

The DIO32276 is a high-performance, double-pole

double-throw (DPDT) analog switch with negative

V_CCswing audio capability. The DIO32276 is

featured in ultra-low audio R_ONof 0.8 Ω (typical) at

3.3 V . The DIO32276 operates over a V_CCrange 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.

R_ON= 0.8 Ω (Typ.) at 3.3 V

THD+N = -110 dB; 2 V_RMS, 600 Ω load; f = 1 kHz

X_TALK= -110 dB at 1 V_RMS, 50 Ω load; f = 1 kHz

Off isolation = -110 dB at 1 V_RMS, 50 Ω load;

f = 1 kHz



External capacitor connection for pop and

click noise suppression



Power-off protection on common ports

DQFN 1.8*1.8-12 package

V_CC= 0 V/float, all switch-I/O Hi-Z

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).

Applications

Mobile phones

Tablets

Notebook PCs

Media players

Docking stations

TVs

Set-top boxes

LCD monitors
