Video speed 6-bit Flash A/D converter by CA3306

Schematic Diagrams      Comments Off on Video speed 6-bit Flash A/D converter by CA3306

This circuit use the CA3306 a family of CMOS parallel (flash) analogue to digital converters designed for low power, high speed applications. The CA3306CE operates at sampling rates up to 10 million samples per second and the CA3306E up to 15 million samples per second permitting analogue signals with bandwidths… Read more »

12V to +-20V converter (for audio amplifier)

Schematic Diagrams      Comments Off on 12V to +-20V converter (for audio amplifier)

author: Jonathan Filippi – www.cool-science.tk The limitation of car supply voltage (12V) forces to convert the voltages to higher in order to power audio amplifiers. In fact the max audio power x speaker (with 4 ohm impedance) using 12V is (Vsupply+ – Vsupply-)^2/(8*impedance) 12^2/32 = 4.5Watts per channel, that is… Read more »

I Find Circuit DC / DC converter for my friend from internet. One good site at http://www.maxim-ic.com about IC Very nice for electronics user. I like many circuit in this site. The MAX668 boost circuit to implement a switch-mode power supply that provides a +15V at 0.5A output from a… Read more »

DC-DC Converter Basics

Schematic Diagrams      Comments Off on DC-DC Converter Basics

A DC-to-DC converter is a device that accepts a DC input voltage and produces a DC output voltage. Typically the output produced is at a different voltage level than the input. In addition, DC-to-DC converters are used to provide noise isolation, power bus regulation, etc. This is a summary of… Read more »

1.2V Drive 7 High efficiency white LED flashlight

Schematic Diagrams      Comments Off on 1.2V Drive 7 High efficiency white LED flashlight

High efficiency white LEDs have advanced to the point where they can replace glow bulbs and other light sources not only as indicators, but also for illumination. While many of the claims made about the LEDs’ efficiency, light quality, lifetime and economy are mostly exaggeration, the truth is that for… Read more »
