Digital Programmable Gain Amplifier
I read your post which is about, Digital gain control of Op-amp. I have some questions to ask, if possible. Please reply ASAP. I am student and I have a lab project to work...
Function Generator using ICL8038
ICL8038 and XR-2206 can help you build a Function Generator or Wavform Generator. It is needed along with the Oscilloscope and Power Supply on the Workbench. The ICL8038 waveform generator is a monolithic integrated...
Voltage to Frequency Converter ICL8038
This was a small circuit made for driving an Impact counter. The heart being ICL8038. It must have been a Motor driving a Conveyor, the motor has a feedback attachment called Tachogenerator. Only part...
VCO – Voltage Controlled Oscillator using Opamps
This is a Voltage to pulse converter using opamps for measuring speed or rate from a Tacho Motor mechanical coupled to a Conveyor System. See the complete circuit in my site to study other...
Electronics Work Bench
How can I get a software for an electronics work bench for my pc. mail from EA I did not understand about the ‘electronics work bench’ pc based instrument. Try simulation based virtual lab...
Analog mV Switch for Digital Meters
Let us assume you have to Measure Amps and Volts in four independent circuits. This becomes a Multi Channel Voltmeter and Ammeter. This circuit uses a 4052 as a DC Analog Multiplexer, the inputs...
Digital to Analog Converter with uC Watchdog
This is the continuation of the earlier post. Part of 80C39 based Process Controller. In this schematic you can see the Watchdog and D/A Converter. 80C39 and MCS48 based Process Controller is the main...
