TDA1522 is a playback amplifier for car radio/cassette players. It features two independent amplifiers with an open-loop gain of 90 dB (typical), internal DC feedback via a 140 kΩ resistor, AC characteristics determined by an external RC network, electronic on/off switching with transient suppression, head input at DC ground, minimum external component requirement, stability down to a gain of 30 dB, low input noise and distortion, and a wide supply voltage range.
