INTEGRATED CIRCUIT
SJ2038
双3.5W音频功率放大电路
■ 概述
SJ2038 是双 BTL 的音频功率放大器。当电源电压为 6V 时,在保证 THD 小于 10%的情况下,
可向 4Ω负载提供 3.5W 的输出功率或者可向 8 Ω负载提供 2.2W 的输出功率。该音频功率
放大器外围元器件极少,高品质的输出功率。
SJ2038 电路的特点为外部控制,低功耗关断模式和内部过热保护,并且在电路中减少了“开
机浪涌脉冲”。
■ 功能特点
‹ 负载为 4Ω 电压 6V 典型为 3.5W
‹ 关断电流典型为 0.7µA
‹ 工作电压范围 2.0V~6.0V
‹ 开机浪涌脉冲抑制电路
‹ 过热保护电路
‹ DIP 封装
