Audio Jack Detector and Pop Noise Control Switch

DESCRIPTION

FEATURES

The DG2591 is an audio jack detector and pop noise control

switch IC.

• Operates with 1.8 V 5 ꢀ

• Low quiescent current of 2 μA/max.

When there is no ear phone detected, the DG2591 connects

the microphone bias line to ground through the MIC pin. The

DG2591 also gives a logic HIGH signal to the baseband

controller through the OUT pin.

• Integrated sense comparator for audio L of

1.4 V 5 ꢀ threshold

• 1 Ω/max. MIC bias switch provides a quick

discharge and clamping

The DG2591 senses the DC levels at both L_Detect and

GND_Detect. When an ear phone is plugged in, the voltage

at both pins will go low. The DG2591 will indicate the

presence of the ear phone by pulling OUT low and the MIC

switch will turn off.

• (Integrated deglitch circuit)

• ESD Protected

- Human body model > 5 kV

- Charged device model > 1 kV

- IEC 61000-4-2 air discharge > 15 kV

- IEC 61000-4-2 contact discharge > 8 kV

The DG2591 is available ultra small miniQFN6 of

1 mm x 1.2 mm size.

• Ultra compact miniQFN6 of 1 mm x 1.2 mm

• Material categorization: for definitions of compliance
