Note1."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.

Note2. Assumes T_TABequals 60 max. For operation at higher tab temperature and at ambient temperatures greater than 25, the NTE7143 must be derated based on a maximum 150 junction temperatur. Thermal resistance depends upon device mounting techniques. R_thJC is typically 2/W.

Description

The NTE7143 is a monolithic power amplifier in a 5Lead TO220 type package offering very low distortion and high quality performance for consumer audio applications.

This NTE7143 delivers 20W into a 4Ωor 8Ω load on ±25V supplies. Using an 8Ω load and ±30V supplies,over 30W of power may be delivered. The amplifier NTE7143 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 extremely 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 NTE7143 is internally compensated and stable for gains of 10 or greater.
