TECHNICAL DATA
2 x 1 W portable/mains-fed stereo
power amplifier
The KKA7053N is an integrated class-B stereo power amplifier in a 16-lead
dual-in-line (DIL) plastic package. The device, consisting of two BTL
amplifiers, is primarily developed for portable audio applications but may also
be used in mains-fed applications.
• No external components
• No switch-ON/OFF clicks
• Good overall stability
• Low power consumption
• Short-circuit-proof

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.

Notes to the characteristics
1. 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.
