The TDA5140A yet embody an Uncommitted Transconductance Amplifier (OTA) that can be appled as a control amplifier. The output is adequate for directly driving an external power transistor. The TDA5140A is built for systems with low current consumption, there are: use of I2L logic, adaptive base drive for the output transistors, likelihood of using a pick-up coil without bias current. [...]

The laser driver circuit diagram shows the schematic of an IC-NZN application, an all-purpose laser driver circuit. It operates from 3.3 to 5.5 V and can drive N, M, and P-type laser diodes with or without monitor diode. The latest generation of all-purpose integrated laser driver solutions supports switching frequencies up to 155 MHz and laser currents up to 300 mA. [...]

By controlling the size of the resistor in one of the four filters the frequency could be adjusted. In order to get the correct size signal, the we must use a potentiometer to be placed to the one of the resistors while also measuring oscilloscope’s output. This will be used to know what size of resistor should be worked at 60Hz. [...]
