好东西分享：CS42L52
要有不俗的音质表现，并要足够大的音量，同时，注意到这是手持产品，能耗必须考虑。[52RD.com]
看起来这是一些矛盾的难题。[52RD.com]
从芯片角度讲，[52RD.com]
cirrus logic 公司刚推出一款芯片，专门针对手机市场，GPS等。相信可以解决这些问题。[52RD.com]
主要指标：[52RD.com]
Low Power Codec with Digital Speaker Amp
1.8V or 2.5V core power supply
2.5V or 5V Class D amplifier supply
1.8V to 3.3V digital interface supply
40-lead QFN package, 6x6, RoHS compliant

Stereo Digital Class-D Speaker driver
Full bridged output configuration
High performance output, 0.1%dB THD+N
2 x 110mW into 8W at 3.6V
2 x 94mW into 8W at 2.5V
High power output, 10% THD+N
2 x 550mW into 8W at 3.6V
2 x 230mW into 8W at 2.5V
No external components
82% Efficiency
Low R(ds) On - .9Ω
Direct connect to battery
DC supply level monitoring & compensation

EUTECH的东西还不错，EUA4890A和NS的LM4990是pin to pin的，而用两个EUA2010做能的音质比较NS的4888要好的多，而且两颗的价格比488便宜近一半，更是超值。
