Preliminary specification

TDA1523

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.

GENERAL DESCRIPTION

The TDA1523 is a playback amplifier for car radio/cassette

players.
