Trimmer Potentiometers, or trimmers, are small, variable resistors used for adjusting current and voltage levels in electronic circuits. The EVM-EGSA00B16 is a trimmer potentiometer from Texas Instruments that offers a wide range of applications in many types of circuits. This article will discuss the application fields and working principle of the EVM-EGSA00B16 trimmer potentiometer. The EVM-EGSA00B16 trimmer potentiometer is a 3-terminal, slide-mono-mechanical trimmer potentiometer. It is designed for adjusting contact resistance points of contact on printed-circuit boards. The trimmer has a two-point terminal on each end, and a common central terminal. The left and right terminals of the trimmer receive the voltage signals, while the center terminal provides the output. The EVM-EGSA00B16 trimmer has a wide range of applications, including in audio circuits, communication circuits, and oscillators for fine tuning.In audio circuits, the trimmer comes in handy when adjusting the balance of the left and right channel of the audio signal. The two-point terminals of the EVM-EGSA00B16 trimmer are connected to left and right channel amplifier output pins, respectively, while the center terminal is connected to the amplifier’s common output pin. When the user adjusts the trimmer, it modifies the voltage levels of the left and right channels, thus obtaining a balanced, stereo signal.In communication circuits, the trimmer is used, among other things, for adjusting the impedance of the transmission line or cable. This impedance adjustment ensures that signal attenuation or distortion due to the transmission line is compensated for. The trimmer is typically adjusted by connecting it to the ground in the DC path, then measuring the return loss of the signal on the output side. The trimmer is then adjusted until the return loss is minimized, and the signal is optimized.The EVM-EGSA00B16 trimmer is also used in oscillator circuits for fine tuning. Here the trimmer is connected in parallel between the reference voltage source and the oscillator’s input pin. By adjusting the trimmer, a consistent oscillator frequency can be obtained.The working principle of the EVM-EGSA00B16 trimmer is relatively simple. The trimmer has a sliding contact, which is moved by the user to adjust the resistance. As the contact is moved, the resistance of the trimmer is adjusted, resulting in a corresponding change in voltage and current levels. The resistance of the EVM-EGSA00B16 trimmer range is adjustable from 15R to 500R.In conclusion, the EVM-EGSA00B16 trimmer potentiometer from Texas Instruments is a versatile device that offers a wide range of applications in many types of electronic circuits. The trimmer is used for adjusting contact resistance points of contact on printed-circuit boards, as well as for balancing the left and right channel of an audio signal, adjusting the impedance of transmission lines, and fine tuning oscillators. The working principle of the trimmer is relatively simple, and involves adjusting the resistance of the trimmer by moving the sliding contact.
