... The typical output power is 2 into 4 . 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 and consumes a low quiescent current ...

... Functional description 6.1 Introduction The TDF8591TH is a dual channel audio power amplifier using class-D technology. The audio input signal is converted into a Pulse Width Modulated (PWM) signal via an analog input stage and PWM modulator. To enable the output power transistors to be driven, this digital PWM signal is applied to a control and handshake block and driver circuits for both the high-side and low-side. An external 2nd-order low-pass fi ...

... Mono Bridge-Tied Load (BTL) amplifier • Dual Single-Ended (SE) amplifiers The TDF8591TH also contains circuits common to both channels such as the oscillator, all reference sources, the mode functionality and a digital timing manager. For protection a thermal foldback, temperature, current and voltage protection are built in. ...
