PARAMETER SINGLE ENDED BRIDGE VOUT max Peak Output Voltage (before clipping) 1 (Vs-2VCE sat) 2 Vs-2VCE sat IOUT max Peak Output Current (before clipping) 1 2 Vs-2V CE sat RL POUT max RMS Output Power (before clipping) 1 (Vs-2VCE sat)2 4 2RL Vs-2V CE sat RL (Vs-2VCE sat )2 2RL Where: VCE sat=output transistors saturation voltage Vs=allowable supply voltage RL=load impedance Voltage and current swings are twice for a bridge amplifier in comparison with single ended amplifier. In order words, with the same RL the bridge configuration can deliver an output power that is four times the output power of a single ended amplifier, while, with the same max output current the bridge configuration can deliver an output power that is twice the output power of a single ended amplifier. Core must be taken when selecting Vs and RL in order to avoid an output peak current above the absolute maximum rating. From the expression for Io max, assuming Vs=14.4V and VCE sat=2V, the minimum load that can be driven by UTC TDA2005 in bridge configuration is: RL min= Vs-2V CE sat Io UT max = 14.4 - 4 =2.97Ω 3.5 The voltage gain of the bridge configuration is given by (see Figure 3): Gv= V0 V1 =1+ R1 + R2× R4 R2 + R 4 R3 R4 For sufficiently high gains (40 ~ 50dB) it is possible to put R2=R4 and R3=2R1, simplifing the formula in: Gv=4 R1 R2 Gv (dB) 40 50 R1(Ω) R2=R4(Ω) R3(Ω) 1000 1000 39 12 2000 2000 Bridge Configuration VD Vi + - + - RL R1 R3 R4 R2 7 of 16 深圳市品良电子有限公司 联系电话：０７５５－２１２３６２５０ ｗｗｗ．ｂｉｎ－ｌｏｎ．ｃｏｍ．ｃｎ TDA2005 LINEAR INTEGRATED CIRCUIT APPLICATION INFORMATION Bridge Amplifier without Boostrap +Vs C6 0.1μF C9 100μ F C1 2.2μ F 1 INPUT C3 10μF 9 7 11 3 + 1/2 TDA2005 - 10 C4 220 μF R1 1K Ω R4 1Ω 2 C2 2.2μ F 5 + 1/2 TDA2005 - C7 0.1μF 8 C5 220 μF 4 R2 2K Ω R6 12Ω RL C8 0.1μ F R5 1Ω R3 12Ω 6 Low Cost Bridge Amplifier (Gv=42dB) +Vs C9 220 μF INPUT C1 0 .1μ F 7 9 11 3 C3 0.1μF C2 10μ F C4 0.1 μF 1 + 10 - R1 1Ω OUT 2 R2 C5 C6 180 Ω 220μF 1nF R3 180 Ω 4 C7 0.1μ F 5 - 8 + UTC TDA2005 6 OUT R4 1Ω C8 0.1μ F 8 of 16 深圳市品良电子有限公司 联系电话：０７５５－２１２３６２５０ ｗｗｗ．ｂｉｎ－ｌｏｎ．ｃｏｍ．ｃｎ TDA2005 LINEAR INTEGRATED CIRCUIT APPLICATION INFORMATION(Cont.) 10+10W Stereo Amplifier with Tone Balance and Loudness Control Vs=+14 .4V R1 120K Ω 0 .1μ F INPUT(L) 9 56K Ω 10μF 3 47nF 22nF P1 100 KΩ + 1/2 TDA2005 - 2.2μF P5 0.15 μF 100 μF 11 10 + 1/2 TDA2005 - 0.22 μF 47nF 47KΩ 2 22nF P2 C9 2200μ F C5 100 μF 4 56K Ω 100 KΩ 100μ F 8 P3 100 KΩ 2.7KΩ INPUT(R) 7 0.22 μF 47K Ω C6 100 μF R3 1KΩ C7 0.1 μF R4 3.3Ω R7 1Ω R5 1KΩ 4Ω 4Ω C8 0.1μ F R6 3.3 Ω 6 2.2μ F 4Ω 2200μ F R8 1Ω P4 100 KΩ 2 .7K Ω 4Ω 0.15μ F Tone Control Response (circuit of Fihure 8) 12 9 6 dB 3 MID 0 -3 TREBLE BASS -6 -9 -12 10 102 103 f (Hz) 104 5 10 9 of 16 深圳市品良电子有限公司 联系电话：０７５５－２１２３６２５０ ｗｗｗ．ｂｉｎ－ｌｏｎ．ｃｏｍ．ｃｎ TDA2005 LINEAR INTEGRATED CIRCUIT APPLICATION INFORMATION(Cont.) 20W Bus Amplifier Vs=+14 .4V 120 KΩ 0.1 μF 9 10 μF 3 18KΩ 7 0.1μF 5 + 1/2 TDA2005 - 22 μF 100μ F 2200 μF 8 1K Ω 4 10 KΩ 10KΩ 47 μF MIKE 200 Ω M 47nF 1K Ω 50KΩ 10KΩ BC109 1KΩ 22 μF 3 .3Ω 0.2μF 1 22KΩ 100μ F 11 + 1/2 TDA2005 - 0.1μF 50 KΩ 8Ω 8Ω 8Ω 8Ω 8Ω 8Ω 8Ω 8Ω 1Ω 2200μ F 10 100μF 2 470PF 100 μF 0.1μF 100μ F R5 1KΩ 0.1μF 6 3 .3Ω 1Ω Simple 20W Two Way Amplifier (Fc=2kHz) +Vs=+14.4V 0 .1μ F R2 10KΩ 11 9 7 C3 2 .2μ F 5 C2 5.6nF 1/2 UTC 1205 8 INPUT R1 680Ω R3 1 KΩ C7 0.1μF R4 10Ω R7 1Ω C10 100 μF R5 1KΩ C8 0.1μF 4 tC =2KHz C1 5.6nF C9 2200μ F C5 100 μF C4 2 .2μ F 1 1/2 UTC 1205 10 P1 10KΩ WOOFER 2 R8 10Ω C6 100 μF cn 2.2 μF 3 6 TWEETER R6 10Ω 10 of 16 深圳市品良电子有限公司 联系电话：０７５５－２１２３６２５０ ｗｗｗ．ｂｉｎ－ｌｏｎ．ｃｏｍ．ｃｎ TDA2005 LINEAR INTEGRATED CIRCUIT APPLICATION INFORMATION(Cont.)

If the supply voltage peaks to more than 40V, then an LC filter must be inserted between the supply and pin9, in order to assure that the pulses at pin 9 will be held withing the limits shown. A suggested LC network is shown in Figure 2, With this network, a train of pulses with amplitude up to 120V and width of 2ms can be applied at point A, This type of protection is ON when the supply voltage (pulse or DC) exceeds 18V. For this reason the maximum operating supply voltage is 18V. Figure 2 Figure 3 Vs(V) 4.0 FROM SUPPLY LINE A L=2mH t1=50ms t2=1000ms TO PIN 9 C 3000µ F 16V 14.4 11 12 t SHORT CIRCUIT (AC AND DC CONDITIONS) The UTC TDA2005 can withstand a permanent short circuit on the output for a supply voltage up to 16V. POLARITY INVERSION High current (up to 10A) can be handled by the device with no damage for a longer period than the blow-out time of a quick 2A fuse (normally connected in series with the supply). This feature is added to avoid destruction, if during fitting to the car, a mistake on the connection of the supply is made. OPEN GROUND When the ratio is in the ON condition and the ground is accidentally opened, a standard audio amplifier will be damaged. On the UTC TDA2005 protection diodes are included to avoid any damage. INDUCTIVE LOAD A protection diode is provided to allow use of the UTC TDA2005 with inductive loads. DC VOLTAGE The maxim operating DC voltage for the UTC TDA2005 is 18V. However the device can withstand a DC voltage up to 28V with no damage. This could occur during winter if two batteries are series connected to crank the engine. THERMAL SHUT-DOWN The presence of a thermal limiting circuit offers the following advantages: (1). An overload on the output (even if it is permanent), or an excessive ambient temperature can be easily withstood. (2). The heatsink can have a smaller factor of safety compared with that of a conventional circuit. There is no device damage in the case of excessive junction temperature; all that happens is that Po (and therefore Ptot) and Id are reduced. The maximum allowable power dissipation depends upon the size of the external heatsink (i.e. its thermal resistance); Figure 4 shows the dissipation power as a function of ambient temperature for different thermal resistance. LOUDSPEAKER PROTECTION The circuit offers loudspeaker protection during short circuit for one wire to ground. 12 of 16 深圳市品良电子有限公司 联系电话：０７５５－２１２３６２５０ ｗｗｗ．ｂｉｎ－ｌｏｎ．ｃｏｍ．ｃｎ TDA2005 LINEAR INTEGRATED CIRCUIT TYPICAL CHARACTORISTICS Figure 5.
