FUNCTIONAL DESCRIPTION The KKA7053N is a stereo output amplifier, with an internal gain of 39 dB, which is primarily for use in portable audio applications but may also be used in mains-fed applications.
The current trends in portable audio application design is to reduce the number of batteries which results in a reduction of output power when using conventional output stages.
The KKA7053N overcomes this problem by using the Bridge-Tied-Load (BTL) principle and is capable of delivering 1.
2 W into an 8 Ω load (V P = 6 V).
The load can be ...
