RSS订阅原创 PADS layout不显示Solder层或其他功能层时，怎么破？
PADS layout不显示Solder层或其他功能层在使用PADS layout时，需经常切换不同的层进行设计，突然发现某些层找不到了？比如Solder层，如图示:那么我们所需的Solder层到底哪去了？这个问题其实很简单，对PADS熟悉的小伙伴应该第一反应就是层没有调用出来嘛，那么接下来我们看下如何调用~第一步：设置-层定义；第二步：“启动/禁用”（箭头所示）；第三步：勾选你...

Audio ADC everest ES7154
The ES7154 is a low cost 14-pin stereo
digital to analog converter. The ES7154 can
accept I²S serial audio data format up to 24-
bit word length. The device uses advanced
multi-bit ∆-∑ modulation technique to
convert data into two channel analog
outputs. The multi-bit ∆-∑ modulator makes
the device with very low sensitivity to clock
jitter and very low out of band noise.
The devices integrates a charge pump to
generate negative supply from 5V supply,
thus providing ground centered 2 Vrms
analog output
