FUNCTIONAL DESCRIPTION
The KKA7053N is a stereo output amplifier, with an internal gain of 39 d B, 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 overes 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 short-circuited under all input conditions.
