Triple Power Supply
Inexpensive miniature transformers typically provide one or two secondary voltages, which are sufficient for generating a set of positive and negative supply voltages, as required for operational amplifier circuits. However, if an additional voltage higher than either of the supply...
Sine wave output buffer amplifier
The sine wave output has a relatively high output impedance (1K typical). The circuit provides buffering, gain, and amplitude adjustment. A simple operational amplifier follower could also be used.
The described circuit is designed to generate a sine wave output while...
High power control for sensitive contacts
Two simple arrangements for resistive loads are shown in A and B. The circuit in A will provide load power when the actuating contact is closed, and no power when the contact is open. B provides the reverse of this...
DIY Circuit Car Battery Charger
