IRS2092STRPBF

Overview

The IRS2092STRPBF is a high voltage, high performance Class D audio amplifier driver with an integrated PWM modulator and protection features. It operates within a VCC supply range of 10V to 18V and supports switching frequencies up to 800 kHz. The device provides a high-side source current (Io+) of 1.0 A and a low-side sink current (Io-) of 1.2 A. Selectable deadtime options include 25/40/65/105 ns, while the over-current protection delay is a maximum of 500 ns. It achieves a DC offset of 60 dB, THD+N of 0.01% at 1kHz, 50W, and 4Ω, and residual noise of 200 µVrms.
