ETC ILA1519

ILA1519
2 x 6 Watt Stereo Car Radio Power Amplifier
GENERAL DESCRIPTION
The ILA1519B is an integrated class-B dual output amplifier in a 9-lead single in-line (SIL) plastic medium power package. The
device is primarily developed for car radio applications.

Notes to the characteristics
1.
All characteristics are measured using the circuit shown in Fig. 4.
2.
The circuit is DC adjusted at Vp= 6V to 18V and AC operating at Vp= 8,5V to 18 V.
3.
At 18 V < Vp< 30 V the DC output voltage < Vp/2.
4.
Output power is measured directly at the output pins of the IC.
5.
Frequency response externally fixed.
6.
Ripple rejection measured at the output with a source impedance of 0 ^ (maximum ripple amplitude of 2 V) and a
frequency between 100 Hz and 10 kHz.
7.
Noise voltage measured in a bandwidth of 20 Hz to 20 kHz.
8.
Noise output voltage independent of R^ (V j = 0 V).
