Description:The LM298N IC (Component 102) is utilised in the design of a flexible PWM to 0-5 volt converter circuit. This circuit is specifically created to connect with different microcontrollers, FPGAs, or hardware development boards, serving as the PWM source (Component 101). This circuit utilises an LM324 operational amplifier (Component 103) for the purpose of processing and amplifying potential signals. The LM298N processes the PWM signal, converting it into corresponding voltage levels, and optionally further conditions it using the LM324. The resulting output is subsequently filtered using a low-pass filter (Component 104) to guarantee stability by eliminating high-frequency noise. This yields a steady DC voltage output that is suitable for both powering and controlling DC motors. The invention is well-suited for studying devices that produce PWM signals, as it allows for the measurement of the converted voltage output using a digital or analogue voltmeter (Component 105). This solution is cost-effective, has low time delay, and has a wide range of educational and experimental applications. , Claims:We Claim:
