ILA7053N 2 x 1 W portable/mains-fed stereo power amplifier N SUFFIX PLASTIC DI

ORDERING INFORMATION

TA = ° to 150° C The ILA7053N 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 QUICK REFERENCE DATA PARAMETER CONDITIONS SYMBOL MIN. MAX.

FUNCTIONAL DESCRIPTION The ILA7053N 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 i n 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 ILA7053N overcomes this problem by using the Bridge-Tied-Load (BTL) principle and i s capable of del ivering 1.2 W into an 8 Ω load (V P = 6 V). The load can be short-circuited under all input conditions. Rev. 00

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. Rev. 00
