This sine wave to square wave converter circuit is expected to provide good square waves changing a sine wave delivered from an existing generator. Its primary feature consists in the fact that no power-source is required: in this manner it can be simply connected between a sine wave generator and the device under test. The… Read More »
This is the circuit diagram of 5VDC single polarity to 12VDC dual polarity converter based on IC LM2595-12 from National Semiconductor. This circuit will convert 5V DC single voltage (+) become 12V DC dual polarity output (+), GND, (-).
The ADC0808, ADC0809 data acquisition component is a monolithic CMOS device with an 8-bit analog-to-digital converter, 8-channel multiplexer and microprocessor compatible control logic. The 8-bit A/D converter uses successive approximation as the conversion technique. The converter features a high impedance chopper stabilized comparator, a 256R voltage divider with analog switch tree and a successive approximation… Read More »
This circuit was built in the lab using the components shown in Figure 1. The -12V output varied between -11.99V and -11.97V under a load variation between 50 mA and 100 mA and a line variation between 4.5V and 5.5V. The +12V output varied between 11.15V and 11.45V under the same conditions. The +12V output… Read More »
This is the circuit diagram of 3V to 9V DC converter which capable to deliver output voltage about 10.4v on no load and 9.6v @30mA. By using this circuit, You will be able to replace a 9v battery from 3V DC input.
ADC0808 – Simple Analoque to Digital Converter This is a very simple analoque to digital converter circuit based on 8-bit analog-to-digital converter ADC0808. Typically analogue-to-digital converter (A/D Converter / ADC) requires interfacing through a microprocessor to convert analogue information into digital format. This needs extra hardware and appropriate software, resulting in more complexity and hence… Read More »
