Issues: 1.Analog Device's AD9599 Devkit are too bulky and expensive. 2.Aliexpress AD9599 Devkit's output are distorted and clipped heavily during loading due to improper filter design. Solution: 1.Implement Analog Devices recommended 7th order lowpass filter using tighter tolerance component, proper...

Issues: 1.Prototype need to be made quickly 2. It's should be cheap Solution: 1.Leverage rapid prototyping technology such as 3d printing to shorten cycle time between design,manufacturing,testing and reiterating 2.Used proven off the shelf RC component such as outrunner BLDC motor, Li-Ion cells, a...

Issues: 1.Amplifier PCB should be small enough to be under 6cmx6cm 2.Should be able to supply enough current while keeping distortion low 3.Amplifier should be able to be used with In Ear Monitor or Headphone Solution: 1. Implement separate gain and buffer section to reduce load. 2. Use parallel opa...
