NTE990 Dual Audio Power Amplifier PDIP-14
Info als pdf File
Description:
The NTE990 is a monolithic dual power amplifier designed to deliver 2W/channel continuous into 8 Ohm loads. This device is designed to operate with a low number of external components, and still provide flexibility for use in stereo phonographs, tape recorders, and AM-FM stereo receivers, etc. Each power apmlifier is biased from a common internal regulator to provide high power supply rejection, and output Q point centering. The NTE990 is internally compensated for all gains greater than 10.

Note 1. | For operation at ambient temperature greater than +25°C, the NTE990 must be derated based on a maximum 150°C junction temerature using a thermal resistance which depends upon device mounting techniques. |
Anmerkung zu den NTE/ECG Austauschhalbleiter:
NTE-Austauschhalbleiter (früher ECG Philips und Sylvania) sind sorgfältig
ausgesuchte und erprobte Halbleiter, die einen sicheren Ersatz
für Originaltypen verschiedenster Hersteller und Ursprünge für
fast alle Applikationsbereiche im Wartungsdienst bieten.
Alle NTE-Austausch-Halbleiter sind einzeln in durchsichtigen
Plastikbeuteln verpackt, auf welchen die wichtigsten Daten
vermerkt sind.
Falls Sie einen Halbleiter suchen, können Sie entweder die NTE QuickCross
Software bei uns als CD kaufen (Best.Nr. 08.NTE.CD) oder
sie gratis vom Internet runterladen.
