Low-voltage analogue switch in 0.35mm thin miniQFN10 package
Typical miniQFN10 and WCSP packages feature profiles of 0.55 mm. The new ultra-thin miniQFN10 package of the DG2592 and DG2750 is 36 % thinner, saving valuable PCB space and allowing for slimmer end products. Compared to WCSP packages, the enhanced miniQFN10 offers easier surface mounting and is better suited for the flexible PCBs commonly utilized in portable designs. The package exceeds current RoHS standards and is completely lead (Pb)-free.
The DG2592 is an audio jack detector and pop noise control switch IC that features integrated circuits for detecting the presence of a stereo headset with a microphone and send/end control button. The device features a wide operating range of 1.6 V to 5.5 V, low quiescent current of 10 μA maximum at 1.8 V, and a 1.2 Ω max. MIC bias switch for quick discharge and clamping. The detector offers ESD tolerance > 8 kV (human body model).
The DG2750 is a low-on-resistance, bidirectional device that is capable of switching negative swing audio without the need for a coupling capacitor. Designed to operate from a single 1.8 V to 5.5 V power supply, the analogue switch conducts audio signals in both directions with very low distortion. Built on sub-micron CMOS low-voltage process technology, the device offers a very low quiescent current and provides latch-up protection > 600 mA per JESD78.
