Ghani Lawal- Will be using LM324DR2G IC for filter op amps, 1.2mA supply current
- 6 ICs x 1.2mA/IC = 7.2 mA
- Worst case scenario, audio signal voltage is >=3.5V, max current output by all filters is 6mA
- 7.2mA + 6mA = 13.2mA
- Max Current output of Rhi controller will output is 1.4 mA + 17uA supply current from the Op-amp
- Max Current Sourced From Dual Rail Power Supply: 13.2mA + 1.417mA = 14.617 mA
- Will establish -5V with LT1054IPE4 - it is a converter and regulator in one, just needs and external resistor network
- ***One of the smoothing capacitors is supposed to be 2uF, but the cheapest one is $1.32, therefore I will be using 2 1uF caps to replace it
- ****In order to simulate in LTSpice consistently make sure the box for "Skip initial operating point solution" is checked
New Op Amp and Negative Voltage ICs
A project log for Music Spectrum and dB Visualizer
Receive input from a 3.5mm jack, divides the music into 7 frequency bands, shows the loudness of each frequency band in DB using LEDS.
