The ON Semiconductor NCP2890DMRZ is a high-quality audio amplifier designed for portable applications. It is a bridge-tied load (BTL) amplifier capable of delivering a continuous average power to an 8 Ohm BTL load with less than 1% distortion (THD+N) from a 5V DC power supply.

Key Features

• Output Power: Delivers 1 Watt of continuous average power to an 8 Ohm load with 0.1% THD+N.
• Low Quiescent Current: The amplifier has a low quiescent current of 4.0mA at 5V, making it ideal for battery-powered devices.
• Superior Pop & Click Noise Protection: Ensures low noise performance during turn-on and turn-off transitions, improving user experience.
• Thermal Overload Protection: Features an in-built thermal overload protection mechanism that safeguards the device from damage due to overheating.
• Short Circuit Protection: The amplifier includes a short circuit protection system that prevents damage from output to GND or VCC shorts.
• Unity-Gain Stable: The device can be configured in unity-gain without external compensation.

Applications

The NCP2890DMRZ is particularly suitable for mobile phones, PDAs, portable media players, laptop computers, and other portable electronic devices where high-quality audio amplification is required in a compact footprint.

Package and Quality

The device is offered in a small 10-pin Micro Lead Frame Package (MLP), which is RoHS compliant and designed for space-constrained applications. ON Semiconductor's commitment to quality ensures that the NCP2890DMRZ meets the highest standards for reliability and performance.
