GENERAL DESCRIPTION
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.
Using the selection pin (GAINSEL) the maximum gain can
be set at 20 or 30 dB. The headphone sense input (HPS)
can be used to detect if a headphone is plugged into the
jack connector. If a headphone is plugged into the jack
connector the amplifier switches from the BTL to the SE
mode and the BTL loudspeakers are switched off. This
also results in a reduction of quiescent current
consumption.
The TDA8552T is contained in a 20-pin small outline
package. For the TDA8552TS, which is contained in a
20-pin very small outline package, the maximum output
power is limited by the maximum allowed ambient
temperature. More information can be found in Section
“Thermal design considerations”. The SO20 package has
the four corner leads connected to the die pad so that the
thermal behaviour can be improved by the PCB layout.
