Sep 1, 2012 · Is it worth asking the question? I read some positive comments on LM1875 but comments that some in the TDA series is more life like...

Apr 13, 2007 · Hi all, This is based on Engels' idea of using the ECH83 as a preamp (a low-voltage triode/heptode with a B+ of only 12V). For my first valve project I'm playing with Engels' design, …

Apr 22, 2019 · In fact, both Tda2030A and 2040 chips only output maximum 2 Watts on 24 Volts @ 8 ohms and 1 watt on 12 Volts @ 8 ohms load. Not only that, I found that component values given in …

Nov 13, 2019 · I started out building a small test circuit with a TDA2030A running at stabilized +-15V and a resistive 8R or 100R load. The circuit is close to the datasheet example, using 22k and 1k in the …

Mar 4, 2013 · I built the single-supply high-power amplifier from the ST datasheet for the TDA2030A. I stuck with the reference design but replaced the BD907/BD908 transistors with TIP35C/TIP36C …

Jul 21, 2011 · ive already made a bridged amplifier with tda2030A totally for two channels i've used 4 of the chip and within a -18/+18 supply with 4A. on every channel i could get almost a 28W on 4ohm …

Mar 9, 2025 · Does Tda 2030A and 2050 chip amps give exactly same power output on Single as well as dual rail suppy ? 2. What should be heatsink sizes (dimensions) for using two of 2030A & 2050 …

Nov 18, 2009 · If I have already tda2030a in my drawer or for low investor, tda2030a is good sound for the PRICE ) I will use four IC 1:Tweeter 2:Mid 3&4:Woofer (Bridge) i.e. 18x2+35 = 70Watts per channel.

Nov 12, 2014 · I don't mind building a circuit board from sscrath, soldering and stuff. So basically: What is the main difference between LM3886, LM1875, LM3875, LM386 (small amp projects -2W?), …

Aug 5, 2005 · I have built a 4 channel power amplifier using TDA2030A I have used a the same circuit as in the datasheet using singlesupply (figure 15 in the datasheet),I have also replaced the zobel …
