The NTE7052 is a mono output amplifier in a 9鈥揕ead SIP type package designed for use in battery鈥?/div>
fed portable radios and mains鈥揻ed equipment such as televisions. This device needs no external
components because it makes use of the Bridge鈥揟ied鈥揕oad (BTL) principle. Consequently it has,
at the same supply voltage, a higher output power compared to a conventional Single Ended output
stages. The NTE7052 is capable of delivering an output power of 1W into a loudspeaker load of 8鈩?/div>
with a 6V supply or 3W into a 16鈩?loudspeaker at 11V without the need of an external heatsink. The
gain is internally fixed at 40dB. Special attention is given to ON/OFF switch click suppression, and
it has a good overall stability. The load can be short circuited at all input conditions.
