BA3516 Dual Power Amplifier Dip-16

Description

BA3516 Dual Power Amplifier Dip-16 The BA3516 is a monolithic linear integrated circuit designed by ROHM specifically for portable audio applications such as headphone stereos and radio cassette players . This device integrates two preamplifiers and two power amplifiers onto a single chip, operating efficiently from a low supply voltage of 3V . The architecture is optimized for compactness and reliability, making it an excellent choice for modern miniaturized audio equipment. Features: Dual preamplifiers and power amplifiers integrated on one chip for stereo audio. Direct-coupled preamplifiers eliminate the need for input capacitors. No bootstrap capacitors required for power amplifiers, simplifying circuit design. High preamplifier gain of 78dB with low noise (1.0µVrms) and distortion (0.03%). Power amplifiers deliver 40mW per channel with low noise (80µVrms) and distortion (0.5%). Specifications: Parameter Value Supply Voltage (Typical) 2.4V Operating Voltage Range 1.8to3.6V Maximum Supply Voltage 4.5V Quiescent Current 8mA Preamplifier Gain (Open Circuit) 78dB Preamplifier Maximum Output Voltage 300mVrms Preamplifier Total Harmonic Distortion 0.03% Power Amplifier Output Power 40mW Power Amplifier Gain (Closed Circuit) 36dB Power Amplifier Total Harmonic Distortion 0.5% Output Noise Voltage (Power) 80µVrms Ripple Rejection (Power) 48dB Channel Separation 37dB Operating Temperature Range -25to75°C Pin Configuration: Applications: 3V headphone stereo systems for portable audio playback. 3V radio cassette players requiring compact amplification. Low-voltage audio amplification in battery-powered devices. Signal processing in vintage audio equipment repairs. Custom stereo headphone drivers in electronic prototypes.
