The IRS20124 is a 200V high voltage rated digital audio driver that can provide up to 1000W of output power in Class D audio amplifier applications. The device features integrated dead-time generation and bidirectional over current sensing to simplify design. The IRS20124 also features a programmable compensated preset dead-time for improved THD performance over temperature. The device has high noise immunity and features a shutdown function to protect devices from overload conditions. The IRS20124 operates at up to 1MHz and has 3.3V/5V logic compatible inputs.
The IRS20124S is a high voltage, high speed power MOSFET driver designed specifically for Class D audio amplifier applications. It features internal dead-time generation to improve Total Harmonic Distortion (THD) performance and includes bi-directional over-current sensing with programmable thresholds.
