13 sty 2024 · I am trying to optimize this circuit for low noise, good bass response, and clear mids and highs. I have designed and built amplifiers with chip amps like the LM3886, LM386, TDA2050, and TDA2003 before.
27 gru 2006 · This is my LM4562 based preamplifier. Noise free and transparent sound - this is what I can say after first tests. Output offset voltage (even without DC blocking caps) - about 1-3mV. This PCB can be used for every dual op-amp. I used R3,R9: 2k, R4,R10: 680R. schematic.
The LM4562's outstanding CMRR (120dB), PSRR (120dB), and V OS (0.1mV) give the amplifier excellent operational amplifier DC performance. The LM4562 has a wide supply range of ±2.5V to ±17V.
This Audio Operational Amplifier achieves outstanding AC performance while driving complex loads with values as high as 100pF. The LM4562 is available in an 8-lead narrow body SOIC, an 8-lead PDIP, and an 8-lead TO-99.
This series is for applications such as high quality audio amplification, multi-media, imaging, line drivers/receivers and active filters. The output current is for 600Ohm loads with more than 26mA drive with THD+N over a wide voltage range.
This Audio Operational Amplifier achieves out-standing AC performance while driving complex loads with values as high as 100pF. The LM4562 is available in 8–lead narrow body SOIC, 8–lead Plastic DIP, and 8–lead Metal Can TO-99. Demonstration boards are available for each package. ±2.5V to ±17V.
12 lut 2021 · This Audio Operational Amplifier achieves outstanding AC performance while driving complex loads with values as high as 100pF. The IC comes in an 8 – pin hermetically sealed dual in line IC packaging. LM4562 offers many features such as Superior Audio Signal Fidelity, output short circuit protection, and high noise immunity.
