TDF8590TH 2 80 W SE (4 ) or 1 160 W BTL (8 ) class-D amplier Rev. 02 23 April 2007 Product data sheet 1. General description The TDF8590TH is a high-efciency class-D audio power amplier with low power dissipation for application in car audio systems. The typical output power is 2 80 W into 4 . The TDF8590TH is available in an HSOP24 power package with a small internal heat sink. Depending on the supply voltage and load conditions, a small or even no external heat sink is required. The amplier operates over a wide supply voltage range from 14 V to 29 V and consumes a low quiescent current. 2. Features n Zero dead time switching n Advanced output current protection n No DC offset induced pop noise at mode transitions n High efciency n Supply voltage from 14 V to 29 V n Low quiescent current n Usable as a stereo Single-Ended (SE) amplier or as a mono amplier in Bridge-Tied Load (BTL) n Fixed gain of 26 dB in SE and 32 dB in BTL n High BTL output power: 160 W into 8 , 120 W into 4 n Suitable for speakers in the range of 2 to 8 n High supply voltage ripple rejection n Internal oscillator or synchronized to an external clock n Full short-circuit proof outputs across load and to supply lines n Thermal foldback and thermal protection 3.
