Lightbulb Maxim AN1931: USB-Powered High Precision Phono Preamp

lineup here again

My attached circuit diagram shows a nice little new idea from Maxim
High quality RIAA Phono Pre Amplifier
using your computer USB port for power supply, +5 Volt.

This design, as often when comes to MAXIM IC devices,
has very small mini components, chips.
Mainly intended for SMD use.
Power supply regulator MAX8877 is one 5-pin SOT23.
Low-Noise, Low-Dropout, 150mA Linear Regulator
Low-Distortion OP Amp MAX4478 is one 6-pin SOT23.
Low-Noise, Low-Distortion, Wide-Band, Rail-to-Rail Op Amp

See my attachment for basic circuit idea.

And visit the webpage for more info.

Basic information in this webpage:
USB-Powered High Precision Hi-Fi Phono Preamp
It is described in Maxim application note AN1931.
