Introduction to tda1554, tda1554 pinout, tda1554 power ratings, tda1554 applicationsHi Guys! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to TDA1554.

The TDA1554Q is an integrated class-B output amplifier mainly used for car radio applications. This device features 4 x 11 W single-ended or 2 x 22 W bridge amplifiers. It comes in a 17-lead single-in-line (SIL) plastic power package.

I suggest you buckle up and read this entire post till the end as I’ll discuss the complete Introduction to TDA1554 covering datasheet, pinout, features, and applications.

Let’s get started.

Introduction to TDA1554

  • TDA1554 is a 4*11W single-ended or 2*22W power amplifier IC which means the internal circuitry features a 4*11W single-ended or 2*22W bridge amplifier.
  • It is an integrated class-B output amplifier that comes in a 17-lead single-in-line (SIL) plastic power package mainly used for car radio applications.
  • Out of four amplifiers incorporated in the device, two are non-inverting and two are inverting amplifiers.

  • Moreover, each amplifier comes with a gain of 20dB (26dB in BTL).
  • These amplifiers carry low thermal resistance and are thermally protected.
  • This device generates high output power and fixed gain.
  • Plus, a mute or standby switch is incorporated with the device helping you mute the amplifiers anytime you want.
  • This device can handle high energy on outputs and low voltage offsets at outputs and comes with good ripple rejection.
