TDA1523 - Stereo cassette head preamplifier/equalizer

General Description

The TDA1523 is a playback amplifier for car radio/cassette players.

MAX.

UNIT V mA °C % dB ORDERING INFORMATION TYPE NUMBER TDA1523 PACKAGE NAME DIP14 DESCRIPTION plastic dual in-line package; 14 leads (300 mil) VERSION SOT27-1 1996 Feb 26 2 Philips Semicon

Key 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.
  • Lo.
