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 short-circuited under all input conditions. 1 KKA7053N +Vp 0,1 µF 01 KKA7053N + _ 220 µF 16 + RL 1 Input 1 02 G N DS 01 13 12 - RL 2 Input 2 06 DC Volume 07 09 + 14 10 GND-P 1. 2. 3. 03 04 08 11 15 GND-P This capacitor can be omitted if the 220 µF electrolytic capacitor is connected close to pin 01.

With a practical load the total quiescent current depends on the offset voltage. 2. Ripple rejection measured at the output with RS = 0 Ω and f = 100 Hz to 10 kHz. The ripple voltage (200 mV) is applied to the positive supply rail. 3. RS = 5 kΩ. 4. The noise output voltage (RMS value) is measured with RS = 5 kΩ, unweighted and a bandwidth of 60 Hz to 15 kHz. 5. The noise output voltage (RMS value) is measured with RS = 0 Ω and f = 500 kHz with 5 kHz bandwidth. If RL = 8 Ω and LL = 200 mH the noise output current is only 100 nA. 4 KKA7053N 5 KKA7053N N SUFFIX PLASTIC DIP (MS - 001BB) A Dimension, mm 9 16 B 1 8 Symbol MIN MAX A 18.67 19.69 B 6.1 7.11 5.33 C F L C -T- SEATING PLANE N G D NOTES: K M H 0.25 (0.010) M T 1.
