APA2069 Stereo 2.6W Audio Power Amplifier (with DC_Volume Control) Features • • • • • • • • • • • Low Operating Current with 9mA Improved Depop Circuitry to Eliminate Turn-on and Turn-off Transients in Outputs High PSRR 32 Steps Volume Adjustable by DC Voltage with Hysteresis 2.6W per Channel Output Power into 4Ω Load at 5V,BTL Mode Two Output Modes Allowable with BTL and SE Modes Selected by SE/BTL pin Low Current Consumption in Shutdown Mode (1µA) Short Circuit Protection Thermal shutdown protection and over current protection circuitry Power DIP-16 Package Lead Free Available (RoHS Compliant) General Description APA2069 is a monolithic integrated circuit, which provides precise DC volume control, and a stereo bridged audio power amplifiers capable of producing 2.6W (1.8W) into 4Ω with less than 10% (1.0%)THD+N. The attenuator range of the volume control in APA2069 is from 20dB (DC_Vol=0V) to -80dB (DC_Vol=3.54V) with 32 steps. The advantage of internal gain setting can be less components and PCB area. Both of the depop circuitry and the thermal shutdown protection circuitry are integrated in APA2069, that reduce pops and clicks noise during power up or shutdown mode operation. It also improves the power off pop noise and protects the chip from being destroyed by over temperature and short current failure. To simplify the audio system design, APA2069 combines a stereo bridge-tied loads (BTL) mode for speaker drive and a stereo single-end (SE) mode for headphone drive into a single chip, where both modes are easily switched by the SE/BTL input control pin signal.
