Preamplifier and Equalizer 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.
