Integrated Silicon Solution, Inc. Audio Amplifiers IS32AP2123-ZLA3

The IS32AP2123-ZLA3 is a Class-D audio amplifier designed for automotive applications, capable of delivering 24W output power into a 4,Ѷ speaker with less than 1% total harmonic distortion plus noise (THD+N) from a 14.4V power supply. It operates within a voltage range of 4.5V to 24V, making it suitable for start/stop or backup battery systems. The amplifier features onboard load diagnostics accessible via an I2C interface, which allows for monitoring of output impedance and detection of shorts. With a power supply rejection ratio (PSRR) of 70dB and an efficiency of up to 85%, the IS32AP2123-ZLA3 is designed to optimize electromagnetic interference (EMI) and includes automatic load diagnostics, over-temperature protection, and dynamic temperature control. The device is housed in a thermally enhanced eTSSOP-16 package, which does not require a heatsink for typical operation. It is AEC-Q100 qualified, ensuring compliance with automotive standards, and operates within a temperature range of -40¬8C to +125¬8C.
