GENERAL DESCRIPTION

The TDA1522 is a playback amplifier for car radio/cassette players.

FEATURES

• Two independent amplifiers with open-loop gain of 90 dB (typical)

• Internal DC feedback via 140 kΩ resistor from output to feedback point

• AC characteristics that can be determined externally by an RC network

• Electronic on/off switching with transient suppression for switch on

• Head input at DC ground that eliminates the input coupling capacitor

• Minimum external component requirement

• Stability down to a gain of 30 dB

• Low input noise

• Low distortion

• DC input current <2 µA

• Wide supply voltage range.
