6 / 10 page July 1994 6 Philips Semiconductors Product specification 2 x 22 W stereo BTL differential amplifier with speaker protection and dynamic TDA1556Q Notes to the characteristics 1. The circuit is DC adjusted at VP = 6 to 18 V and AC operating at VP = 8.5 to 18 V 2. At 18 V < VP < 30 V the DC output voltage ≤ VP/2 3. Conditions: V14 = 0 V; short circuit to ground; switch V14 to MUTE or ON condition, rise time at V14 = ≥ 10 µs 4. Frequency response externally fixed 5. Ripple rejection measured at the output with a source-impedance of 0 Ω (maximum ripple amplitude of 2 V) and a frequency between 100 Hz and 10 kHz 6. Mismatching is given by the following equation: 7. Noise measured in a bandwidth of 20 Hz to 20 kHz 8. Noise output voltage independent of RS (VI = 0 V) 9. Common mode rejection ratio measured at the output with both inputs tied together. VI(RMS) < 3.5 V; f = 100 Hz - 10 kHz MUTE CONDITION Vmute mute voltage 3.3 − 6.4 V VO output signal in mute position VI max = 1 V; f = 1 kHz −− 2mV Vos DC output offset voltage −− 100 mV STANDBY CONDITION Vsb stand-by voltage 0 − 2V Isb DC standby current V14 < 0.5 V −− 100 µA 0.5 V ≤ V14 ≤ 2.0 V −− 500 µA Isw switch-on current − 25 60 µA IPSC supply current short-circuit to ground; note 3 − 10 - mA Loudspeaker protection ∆V 6-8, 10-12 DC voltage across RL −− 1.0 V td delay time − 0.5 − s Protection active ( ∆V4-6 or ∆V7-9≤ 1.0 V I15 current information − 25 −µA V15 voltage information 3.6 −− V Protection inactive ( ∆V6-8 and ∆V10-12≤ 0.1 V) V15 voltage information −− 0.3 V SYMBOL PARAMETER CONDITIONS MIN.
