DG2592DN-T1-GE4

Audio Special Purpose Overview

The DG2592DN-T1-GE4 is an audio jack detector and pop noise control switch IC manufactured by Vishay Siliconix. It integrates circuits to detect stereo headsets with microphones and send/end buttons. The device operates on a single supply voltage ranging from 1.6 V to 5.5 V, with a maximum quiescent current of 10 μA at VDD = 1.8 V. It features an integrated sense comparator for audio L detection with a threshold of 1.4 V ± 5%. The MIC bias switch provides a maximum on-resistance of 1.2 Ω. The component is housed in a compact miniQFN-10 package measuring 1.4 mm x 1.8 mm x 0.55 mm.

Audio Special Purpose Feature Summary

• Integrated audio jack detection with logic output (DET) indicating headset presence
• Low quiescent current of 10 μA maximum at VDD = 1.8 V
• MIC bias switch with low on-resistance of 1.2 Ω max for quick discharge
• ESD protection exceeding 8 kV HBM and 15 kV IEC air discharge

Audio Special Purpose Applications

• Cellular phones
• Tablet devices
• Portable media players
• Digital cameras

Audio Special Purpose Procurement Notes

Verify the specific ordering suffix 'T1' corresponds to the miniQFN-10 package configuration as defined in the manufacturer's ordering information table. Confirm that the reel quantity matches the standard 3000-unit packaging specified for this part number variant. Ensure compatibility with the required operating temperature range of -40 °C to +85 °C for the target application environment.

Audio Special Purpose Selection Notes

Select this component when designing systems requiring dedicated audio jack presence detection and microphone bias management. The device is suitable for applications needing a low-profile solution due to its ultra-thin miniQFN-10 footprint. Designers must account for the separate power supplies VDD and VDD2, ensuring appropriate bypass capacitors are placed near these pins to maintain signal integrity and stable operation.

Audio Special Purpose Part Context

This part belongs to the DG2592 family of audio jack detectors. The 'DN' suffix indicates the miniQFN-10 package variant, while 'DG2592DN1-T1-GE4' represents the UTMQFN-10 version. Both variants share identical electrical characteristics but differ in physical thickness, with the DN version being 0.55 mm thick compared to 0.35 mm for the DN1 version.

Audio Special Purpose Replacement Considerations

The DG2592DN1-T1-GE4 serves as a direct pin-compatible alternative offering a thinner profile (UTMQFN-10). No other cross-model replacements are documented in the provided datasheet.
