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.

1. 物料型号: - 型号为APA2069,这是一款立体声2.6W音频功率放大器,具备直流音量控制功能。

2. 器件简介: - APA2069是一个集成单片电路,提供精确的直流音量控制和立体声桥接音频功率放大器,能够在4欧姆负载下产生2.6W(1.8W)的输出功率,失真度小于10%(1.0%)THD+N。内部增益设置可以减少组件数量和PCB面积。APA2069集成了去啪声电路和热关断保护电路,以减少开机或关机模式操作期间的噪音,并保护芯片免受过温和短路故障的破坏。

3. 引脚分配: - 1号引脚:SHUTDOWN,拉低进入关机模式。 - 2号引脚:BYPASS,偏置电压发生器。 - 3号引脚:RIN-,右通道输入端。 - 4、5、12、13号引脚:GND,接地连接。 - 6号引脚:LIN-,左通道输入端。 - 7号引脚:VOLUME,内部音量增益设置的输入信号。 - 8号引脚:SE/BTL,输出模式控制输入,高电平为SE输出模式,低电平为BTL模式。 - 9号引脚:LOUT-,BTL和SE模式下的左通道正输出。 - 10、15号引脚:VDD,供电电压。 - 11号引脚:LOUT+,BTL模式下的左通道负输出,在SE模式下呈高阻态。 - 14号引脚:ROUT+,BTL模式下的右通道负输出,在SE模式下呈高阻态。 - 16号引脚:ROUT-,BTL和SE模式下的右通道正输出。

4. 参数特性: - 工作电流低,仅为9mA。 - 提高了去啪声电路,消除输出在开机和关机时的瞬态。 - 高电源抑制比(PSRR)。 - 通过直流电压32级可调音量,具有滞后功能。 - 在5V供电、BTL模式下,每通道4欧姆负载下输出功率为2.6W。 - 允许BTL和SE两种输出模式,通过SE/BTL引脚选择。 - 低功耗模式下电流消耗仅为1µA。 - 具有短路保护、热关断保护和过流保护电路。 - 封装为DIP-16封装,提供无铅版本(符合RoHS标准)。

5. 功能详解: - APA2069设计用于笔记本电脑、液晶显示器或电视等领域。其内部结构包含两个运放,可以以桥接模式(BTL)或单端模式(SE)驱动扬声器或耳机。APA2069还集成了内部音量控制,通过VOLUME引脚的直流电压调节音量,范围从20dB到-80dB,共32级。

6. 应用信息: - 适用于需要音频放大的多种应用,如笔记本电脑、显示器和电视等。

7. 封装信息: - 封装为PDIP-16,参考JEDEC Registration MS-001标准。PDF中还提供了详细的封装尺寸信息。
