NA1150 Series
Audio Switching Driver with Load Diagnostics (U.D.)

  • Description

    The NA1150 is a PWM input - mono BTL output audio Switching driver, ideal for use in microcontroller based sound systems such as security equipment, digital signage equipment and household appliance.

    The device provides up to 1.2W into 8 Ω at less than 10% THD+N from a 5Vdc supply.

    The integrated load diagnostic function notifies the MCU of any speaker connection anomalies through an open-drain output port. Fewer external components with a smaller package provide a reliable, space-saving solution for voice speech and sound reproduction designs.

    The NA1150 is ideal for systems equipped with the D-Amp Driver® manufactured by CRI Middleware Co., Ltd.

    CRI D-Amp Driver®

    CRI D-Amp Driver® is an audio middleware that realizes high-quality sound playback system without a speech synthesis IC.
