• Operating Voltage: 2.3V~5.5V • Supply Current - I =1mA at V =3.6V DD DD • Low Shutdown Current - IDD=5µA at VDD=3.6V • Ground Reference Output - No Output Capacitor Required (for DC Blocking) - Save the PCB Space - Reduce the BOM Costs - Improve the Low Frequency Response • Output Power 50mW/Ch into 16Ω at V =3.6V DD • High PSRR: 80dB at 217Hz • Fast Start-Up Time: 4ms • Integrate the De-pop Circuitry • Thermal Protection • Integrated LDO (Low Dropout Regulator) for Microphone Detection Circuit (1.9V) • Surface-Mount Packaging WLCSP1.6x1.6-12 • Lead Free and Green Devices Available (RoHS Compliant) Applications The APA2181 is a stereo, fixed gain, single supply, and cap-free headphone driver, which is available in a WLCSP1.6x1.6-12 package.
The APA2181 is ground-reference output, and no need the output capacitors for DC blocking.
The advantages of eliminating the output capacitor are saving the cost, eliminating component height, and improving the low frequency response.
