TDA1522 Overview
Description
TDA1522 The TDA1522 is a playback amplifier for car radio/cassette players. 23 +85 - - UNIT V mA °C % dB.
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
- Low input noise
- Low distortion
- DC input current <2 µA
