DG2592
Vishay Siliconix
Audio Jack Detector with Send / End Detect
DESCRIPTION
The DG2592 is an audio jack detector and pop noise control
switch IC. It integrates the circuits necessary to detect the
presence of a stereo headset with a microphone and send /
end control button.
When there is no ear phone detected, the DG2592 connects
the microphone bias line to ground through the MIC pin. The
DG2592 also gives a logic high signal to the baseband
controller through the DET pin.
The DG2592 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 DG2592 will indicate the
presence of the ear phone by pulling DET low and the MIC
switch will turn off.
The DG2592 is available in small miniQFN10 of
1.4 mm x 1.8 mm x 0.55 mm and ultra thin UTMQFN10 of
0.35 mm thickness.
FEATURES
• Wide operating voltage range: 1.6 V to 5.5 V
• Low quiescent current of 10 μA, max. at
VDD = 1.8 V
• Integrated sense comparator for audio L of
1.4 V ± 5 % threshold
• 1.2 /max. MIC bias switch provides quick discharge and
clamping
• ESD Protected
