Author: Pablo E. Leibovich and Alberto I. Leibovich Introduction Climate change and its consequences have increased concern about how to replace fossil fuels with cleaner and more sustainable alternatives for electricity generation. Renewable energy sources, such as solar, wind,...

The board presented here is a preamplifier for contact microphones that are used for amplifying the sound of musical instruments which do not contain electrical pickups, such as guitar and violins. Most contact microphones use a piezo element to convert vibration in the body of the...

Texas Instruments' 16 V, 11 MHz op amps are ideal for industrial applications offering high performance and flexibility Texas Instruments' TLV916x (TLV9161, TLV9162, and TLV9164) is a family of 16 V, general-purpose op amps that offer exceptional DC precision and AC performance...

The project described here is a differential line receiver consisting of high-performance INA134 OPAMPs with on-chip precision resistors. The project is fully specified for high-performance audio applications and has excellent AC specifications, including low distortion (0.0005% at...

The project presented here is an SPI programable Gain Amplifier using MAX9939. The MAX9939 is a general-purpose, differential-input programmable-gain amplifier (PGA) that is ideal for conditioning a variety of wide dynamic range signals such as those found in motor current-sense,...

This is a Full wave rectifier project built using MAX44267 dual OPAMP which provides true zero output with a single supply. The circuit converts Bipolar/AC input into full-wave output. CN1 is provided for sinewave input, CN2 helps to connect the power and output. Operating supply 15V...

This is easy to build and very useful project for hobbyists and students to learn and create OPAMP-based projects. The project accommodates a single OPAMP in the MSOP8 package. The project provides the user with multiple choices and extensive flexibility for different applications...

This is a very simple bidirectional speed control of a small DC brushed motor. The project is built using power OPAMP TCA0372 which can drive a load up to 1A. Connecting a small DC motor and trimmer pot will control the motor forward/reverse operation along with speed control. A Trimmer...
