ILA1519B 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. Features Requires very few external components Thermally protected High output power Reverse polarity safe Fixed gain Compatible with TDA1517 (except gain) Good ripple rejection No switch-on/switch-off plop Mute/stand-by switch Protected against electrostatic discharge Load dump protection AC and DC short-circuit-safe to ground and Vp Capability to handle high energy on outputs (Vp = 0 V) QUICK REFERENCE DATA parameter Supply voltage range operating non-operating load dump protected Repetitive peak output current Total quiescent current Stand-by current Switch-on current Input impedance Output power Channel separation Noise output voltage Supply voltage ripple rejection conditions min. typ. max. unit Vp Vp Vp IORM 6,0 - 14,4 - 18,0 30 45 2,5 V V V A Itot 40 80 mA Isb Isw /Z1/ 0,1 100 40 mA mA kΩ W W dB µV dB 50 THD= 0,5%;4 Ω THD=10%;4 Ω f=100Hz f=1kHz to 10 kHz Crystal temperature symbol 5 6 α Vno(rms) SVRR 40 SVRR Tc 48 150 40 PACKAGE OUTLINE: 9-lead SIL-bent-to-DIL; plastic (SOT110B).

All characteristics are measured using the circuit shown in Fig. 4. The circuit is DC adjusted at Vp= 6V to 18V and AC operating at Vp= 8,5V to 18 V. At 18 V < Vp< 30 V the DC output voltage < Vp/2. Output power is measured directly at the output pins of the IC. 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 Rn (V j = 0 V). 3
