概览
NCS2632 是一款无爆裂声的立体声线路驱动器。它采用安森美半导体的 NOCAP 专利技术，通过生成内部负电源轨道，提供接地参考输出，无需外部直流阻断电容。此器件可 5 V 电源下，驱动 3 VRMS 形成 600 Ω 负载。与类似的音频方案相比，NOCAP 方法摒弃了两个外部重耦合电容，显著节省了空间和成本。NCS2632 具有差分输入，外部可调增益范围为 ±1 V/V 至 ±10 V/V。增益由外部电阻调节。此器件还可配置为一个二阶低通滤波器，以完善 DAC 和 SOC 转换器。除 NOCAP 结构外，它还包含特殊电路，以防止在启用/转换转换过程中出现爆裂和咔嗒的噪声。信噪比达 105 dB，提供高保真音频声音。NCS2632 具有高电源抑制比，典型值为 90 dB。此器件还具有欠压保护 (UVP) 功能，可用外部阻桥调节。此器件采用 TSSOP-14 封装。
