unity gain buffer

hi everyone, I am a university student pursuing physics honours I am building an project in which i need to drive an sine signal on 4-ohm woofer from an function generator. so as not having that much core electronics background I studied some basic circuitry like building a power amplifiers...

Hello all, this is my first post here. I have designed a custom 12V battery, along with a LM386 amp circuit, which allows me to play my guitar through an 8ohm speaker fairly well However, when switching pickups from humbuckers to single coils, the audio starts to clip and distort How can I...

Hello all, I have encountered an AHC244 chip used to drive LEDs (Something like in the attached image) so I wondered why not just drive the LEDs with the uC pins? And also I have seen this IC used with some PWM signals as inputs to it! in this case, I am guessing the output would be the same...

Hi All, I hope that I am posting to the right forum. After days of searching, reading, experimenting, I still have not been able to find a proper solution which I can tailor to my issue, so it is time to ask you guys. I made a voltmeter which consists of an Arduino microcontroller and an...

Hello, In my design I need to buffer about 45V-48V and about 30V. For this purpose I want to use two Opamps in Unity Gain Configuration and chose to use 2 ADA4522 (since it has an input range of 0-55V and low a low offset voltage, see attached schematic). In the simulation the buffer circuit...

Hi I am currently designing a circuit where I need to split a single 0V-5V analog signal (coming from a DAC chip) to go to 8 separate IC's. The 8 IC's are on separate PCB's that are connected with a long cable (about 4m max) to the PCB with the DAC. I need the signal that reaches all the IC's...
