2 x 1.4 W BTL audio amplifiers TDA8552T, TDA8552TS

The TDA8552T is a two channel audio power amplifier that provides an output power of 2 × 1.4 W into an 8 Ω load using a 5 V power supply. The circuit contains two BTL power amplifiers, two digital volume controls and standby/mute logic. Volume and balance of the amplifiers are controlled using two digital input pins which can be driven by simple push-buttons or by a microcontroller.

Class-H high-output voltage level line driver

General Description:

The TDA8576T is a two channel class-H high-output voltage line driver for use in car audio applications. The line driver operates as a non-inverting amplifier with a gain of 6 dB and a single-ended output. Due to the class-H voltage lifting principle the voltage swing over the load is more than the supply voltage. With a supply voltage of 9 V the output voltage swing over the load will be more than 14 V (peak-to-peak). The TDA8576T is available in a SO16 package. Line drivers are necessary in car audio systems in which the power amplifiers are driven by long cables. The signal-to-noise ratio of these car audio systems is improved by using the TDA8576T class-H high-output level line driver. The high-output level of TDA8576T enables a reduction of the gain of the power amplifier resulting in an improvement of the power amplifier performance.

2 x 20 W BTL amplifiers

General Description:

The IC incorporates the following functions:

4 × 6 W SE amplifies without SE capacitor, because of the availability of 2 half supply voltage power buffers. 2. 2 × 20 W BTL amplifiers. Automatic switching between 2 and 4 speaker operation. The mode of operation is determined during start-up.

This amplifier is protected for all general short-circuit conditions to battery or ground, overvoltage, 45 V load dump and short-circuits on the speaker outputs. The IC is contained in a 20-pin power HSOP package, but is also available in a 17-pin SIL power package. When packaged in the 20-pin HSOP package additional functions are available:

DDD level selection between 2 and 10% Overrule pin for changing mode of operation (from SE to BTL or from BTL to SE).
