Nisshinbo NA1150 Audio Switching Amplifier
Nisshinbo NA1150 Audio Switching Amplifier is a one-chip device with differential or single-ended Pulse Width Modulation (PWM) input. This audio amplifier drives a loudspeaker with a pulse-width modulated audio signal from the microcomputer. The NA1150 amplifier offers typical 1.2W output power into an 8Ω speaker at 10% THD+N from a 5VDD voltage source. This audio amplifier includes over-current detection, load diagnostics, and thermal shutdown functions.
The Nisshinbo NA1150 amplifier operates within the -40°C to +125°C temperature range. It is AEC-Q100 qualified and complies with general-purpose and consumer application grades. The NA1150 amplifier is used in microcontroller-based sound systems, including digital signage equipment, security equipment, ADAS, and household appliances.
