NTE7143  
Integrated Circuit  
Audio Power Amplifier, 20W  
Description:  
The NTE7143 is a monolithic power amplifier in a 5–Lead TO220 type package offering very low  
distortion and high quality performance for consumer audio applications.  
This device delivers 20W into a 4or 8load on ±25V supplies. Using an 8load and ±30V supplies,  
over 30W of power may be delivered. The amplifier is designed to operate with a minimum of external  
components. Device overload protection consists of both internal current limit and thermal shutdown.  
The NTE7143 design takes advantage of advanced circuit techniques and processing to achieve ex-  
tremely low distortion levels even at high output power levels. Other outstanding features include high  
gain, fast slew rate and a wide power bandwidth, large output voltage swing, high current capability,  
and a very wide supply range. The amplifier is internally compensated and stable for gains of 10 or  
greater.  
Features:  
D Up to 30W Output Power  
D Thermal Protection with Parole Circuit  
D High Current Capability: 4A  
D Wide Supply Range: 16V – 60V  
D Internal Output Protection Diodes  
D 94dB Ripple Rejection  
D AVO Typically 90dB  
D Low Distortion: 0.015%, 1kHz, 20W  
D Wide Power Bandwidth: 70kHz  
D Protection for AC and DC Short Circuits to GND  
Applications:  
D High Performance Audio Systems  
D Bridge Amplifiers  
D Servo Amplifiers  
D Instrument Systems  
D Stereo Phonographs

Note 1. “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur.  
Operating ratings indicate conditions for which the device is functional, but do not guarantee  
specific performance limits.  
Note 2. Assumes TTAB equals 60°C max. For operation at higher tab temperature and at ambient  
temperatures greater than 25°C, the NTE7143 must be derated based on a maximum 150°C  
junction temperatur. Thermal resistance depends upon device mounting techniques. RthJC  
is typically 2°C/W.
