Part Number: TDA8932
Function: Class-D audio amplifier
Package: SO32 Type
Manufacturer: NXP Semiconductors.
The TDA8932B is a high efficiency class-D amplifier with low power dissipation.
The continuous time output power is 2 ´ 15 W in stereo half-bridge application (RL = 4 W)
or 1 ´ 30 W in mono full-bridge application (RL = 8 W). Due to the low power dissipation
the device can be used without any external heat sink when playing music. Due to the
implementation of thermal foldback, even for high supply voltages and/or lower load
impedances, the device continues to operate with considerable music output power
without the need for an external heat sink.
TDA8932 Class-D audio ampliﬁer Rev. 02 — 12 December 2006 Preliminary data sheet 1. General description The TDA8932 is a high efﬁciency class-D ampliﬁer with low power dissipation. The typical output power is 2 × 15 W in stereo half-bridge application (RL = 4 Ω) or 1 × 30 W typical in full-bridge application (RL = 8 Ω). Due to the low power dissipation the device can be used without any external heat sink when playing music. If proper cooling via the printed-circuit board is implemented, a continuous output power of 2 × 15 W is feasible. Due to the implementation of thermal foldback, even for high supply voltages and/or lower load impedances, the device remains operating with considerable music output power without the need for an external heat sink. The device has two full-differential inputs driving two independent outputs. It can be used as mono full-bridge conﬁguration (BTL) or as stereo half-bridge conﬁguration (SE). 2.
