The TDA 2020 is a monolithic integrated operational amplifier in a 14-lead quad in-line plastic pa ckage, intended for use as a low frequency class B power amplifier. Typically it provides 20W output power (d = 1%) at ± 18V/4n; the guaranteed output power at …

The TDA2030A is a monolithic IC in Pentawatt ® package intended for use as low frequency class AB amplifier. With VS max = 44V it is particularly suited for more reliable applications without regulated supply and for 35W driver circuits using low-cost complementary pairs.

20W Hi-Fi AUDIO AMPLIFIER class B power amplifier. Typically it provides 20W output power (d = 1% ) at ± 18V/4n; the guaranteed output power at ± 17V/4 is 15W (DIN norm 45500). The TDA 2020 provides high output current (up to 3.5 A) and has very low harmonic

2022年7月14日 · Here is a simple power amplifier circuit in OCL class B using TDA2020. If we use the 18V 2A Dual Power supply (+18V, -18V, GND). And Speaker 4 ohms. It can give output power 20 watts RMS. Even more importantly. We can get more wattage by using Bridge amplifier. Do you know about it? Imagine you have a stereo amplifier using TDA2020.

2017年3月14日 · 先前重新玩DIY拿TDA2030A来重新破处，可能坛里绝大部分人对此是不屑一顾，毕竟论坛发展了这么多年了，还在论坛里玩的应该都是提高了档次玩各种分立名机线路，因为大家都有钱了，有足够的经济能力赴澳门豪赌，像我这种农村穷小子也只能躲在山沟里斗地主了。 在论坛混了十几年，虽然也很想玩玩高端一些的放大线路，但限于经济能力的支出也只能量力而为。 话就不多说了，先来直接上图，懒得一个一个图的谈听感了。 先前的帖子里用OO板做了标准 …

2014年9月26日 · TDA2020 (IC 1) can deliver a maximum of 20Watt into a 4Ω loads. Like the TBA810, the TDA2020 also incorporated thermal shutdown, and output short-circuit protection. The input impedance of the circuit 20Watt audio amplifier using TDA2020 is determined by resistor R 1 and sensitivity is determined by resistor R 3 and R 2.
