TDF8591TH
General description
The TDF8591TH is a high-efficiency class-D audio power amplifier with low power dissipation for application in car audio systems. The typical output power is 2 x 100 W into 4 Ohm.
The TDF8591TH 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 amplifier operates over a wide supply voltage range from +-14 V to +-29 V and consumes a low quiescent current.
Features
- Zero dead time switching
- Advanced output current protection
- No DC offset induced pop noise at mode transitions
- High efficiency
- Supply voltage from +-14 V to +-29 V
- Low quiescent current
- Usable as a stereo Single-Ended (SE) amplifier or as a mono amplifier in Bridge-Tied Load (BTL)
- Fixed gain of 26 dB in SE and 32 dB in BTL
- High BTL output power: 310 W into 4 Ohm
- Suitable for speakers in the 2 Ohm to 8 Ohm range
- High supply voltage ripple rejection
- Internal oscillator or synchronized to an external clock
- Full short-circuit proof outputs across load and to supply lines
- Thermal foldback and thermal protection
- AEC-Q100 qualified
