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 +V p 01 0, 1 µF KK A7053N 16 + _ 220 µF + RL 1 Inp u t 1 02 G N DS 01 13 - Input 2 06 12 RL 2 DC Volu m e 07 09 + 10 14 03 04 08 11 15 G ND-P G ND-P 1. 2. 3.

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 S UFFIX PLAS TIC DIP (MS - 0 0 1 BB) A Dimens ion, mm 16 9 B 1 8 Symbol A B C MIN 18.67 6.1 MAX 19.69 7.11 5.33 F L D F 0.36 1.14 2.54 7.62 0° 2.92 7.62 0.2 0.38 0.56 1.78 C -T- SEATING N G D 0.25 (0.010) M T K PLAN E G H H J M J K L M N 10° 3.81 8.26 0.36 NOTES : 1.
