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: The voltage gain of the bridge configuration is given by (see Figure 3): Gv= V0 V1 =1+ R1 + R2× R4 R2 + R4 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 UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 7 of 16 QW-R107-035,D TDA2005 LINEAR INTEGRATED CIRCUIT APPLICATION INFORMATION Bridge Amplifier without Boostrap +VS C9 100μF C1 2.2μF INPUT C6 0.1μF 1 C3 10μF 9 7 11 3 + 1/2 TDA2005 - 10 C4 220μF R1 1KΩ R4 1Ω 2 C2 2.2μF 5 + 1/2 TDA2005 - 8 C5 220μF 4 6 C7 0.1μF R2 2KΩ R6 12Ω RL C8 0.1μF R5 1Ω R3 12Ω Low Cost Bridge Amplifier (GV=42dB) UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 8 of 16 QW-R107-035,D TDA2005 LINEAR INTEGRATED CIRCUIT APPLICATION INFORMATION(Cont.) 10+10W Stereo Amplifier with Tone Balance and Loudness Control Vs=+14.4V R1 120KΩ 0.1μF INPUT(L) 9 5.6KΩ 10μF 3 47nF 2.2nF P1 100KΩ + 1/2 TDA2005 - 2.2nF 4 100KΩ P5 0.15μF 0.22μF 47nF 47KΩ 2 2.2nF P2 C9 2200μF C5 100μF 100μF 11 10 + 1/2 TDA2005 - 5.6KΩ 100μF 8 P3 100KΩ 2.7KΩ INPUT(R) 7 0.22μF 47KΩ C6 100μF C7 0.1μF R4 3.3Ω R7 1Ω 4Ω R5 1KΩ 4Ω 4Ω C8 0.1μF R6 3.3Ω 6 2.2nF 2.7KΩ 4Ω 2200μF R8 1Ω P4 100KΩ 100KΩ R3 1KΩ 0.15μF Tone Control Response (circuit of Fihure 8) 12 9 6 dB 3 MID 3 6 9 12 BASS 1 0 12 0 UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw TREBLE 0 13 0 f (Hz) 14 0 5 10 9 of 16 QW-R107-035,D TDA2005 LINEAR INTEGRATED CIRCUIT APPLICATION INFORMATION(Cont.) 20W Bus Amplifier Simple 20W Two Way Amplifier (FC=2kHz) UNISONIC TECHNOLOGIES CO., LTD www.unisonic.com.tw 10 of 16 QW-R107-035,D 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. 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 PD) 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.
