NA1150 Series
Audio Switching Driver with Load Diagnostics

  • Description

    The NA1150 is a CMOS process PWM input - mono BTL output audio Switching driver, ideal for use in microcontroller-based sound systems such as automotive instrument cluster, infotainment applications, security equipment, digital signage equipment and household appliances. 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.
