The Blocking Capacitors device enables smaller end products by integrating a high-performance, low-power DirectPath variable- – 30 mW/Ch into 32 Ω / Ch at 1% THD+N attenuation class-G stereo headphone amplifier, – –42 dB to +6 dB Volume Control variable-gain microphone preamplifier with bias with – 2.0 µV Output Noise at –42 dB Gain advanced accessory detection circuitry, all in a tiny – 91-dB PSRR 5-mm × 5-mm terminal, 0.4-mm pitch WCSP package. – Ground Loop Rejection for Reducing Crosstalk The class-G headphone amplifier maximizes battery • Fully Differential Mic Preamplifier With Variable life by adjusting the supply voltage of the headphone Gain and 3.4-µV Low Noise amplifier based on audio signal level. With 8-µV – Integrated AC-Coupling Capacitor output noise at 0-dB gain and PSRR of 91 dB, the – Ground Loop Rejection for Reducing headphone amplifier provides excellent audio Headphone to Mic Crosstalk performance. DirectPath eliminates the need for DC- blocking capacitors. The microphone preamplifier has • Choice of Two Mic Bias Voltages: 2.0 V and 2.6 V two programmable gains of 12 dB and 24 dB, and – 92-dB PSRR 3.4 µV input referred noise. – Integrated Programmable Mic Bias Resistor The microphone bias voltage has two programmable • Advanced Accessory Insertion, Removal, and settings of 2 V and 2.6 V. The bias output drives up Type Detection to 1.2 mA of current, has a low output noise of 2 µV, • Passive Multi-button Support Using 10-Bit SAR and 92-dB PSRR, providing excellent rejection of ADC power supply noise in wireless handsets. – Implements Proprietary Scheme to Reduce The advanced accessory detection algorithm Error Caused by Audio Playback Signal in automatically detects six supported accessories and Presence of Finite Resistance on Headset enables or disables internal components.
