PA2005 LINEAR INTEGRATED CIRCUIT UNISONIC TECHNOLOGIES CO., LTD 7 of 16 www.unisonic.com.tw QW-R107-035,D „ BRIDGE AMPLIFIER DESIGN The following consideraions can be useful when designing a bridge amplifier. PARAMETER SINGLE ENDED BRIDGE VOUT max Peak Output Volt age (before clipping) (Vs-2VCE sat)1

2 Vs-2VCE sat

IOUT max Peak Output Current (before clipping) Vs-2VCE sat1 2 RL Vs-2VCE sat RL POUT max RMS Output Power (before clipping) (Vs-2VCE sat)2 2RL4 1 (Vs-2VCE sat)2 2RL Where: VCE sat=output transistors saturation voltage Vs=allowable supply voltage R L=load impedance Voltage and current swings are twice for a bridge amplifie r 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 cu rrent 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 R L in order to avoid an output peak current above the absolute maximum rating. From the expression for Io max, assuming Vs=14.4V and V CE sat=2V, the minimum load that can be driven by UTC PA2005 in bridge configuration is: The voltage gain of the bridge configuration is given by (see Figure 3): Gv= V0 =1+ R1 R2× R4 R2 + R4 For sufficiently high gains (40 ~ 50dB) it is possible to put R2=R4 and R3=2R1, simplifing the formula in: Gv=4 R1 Gv (dB) R1(Ω) R2=R4( Ω) R3( Ω) 40 1000 39 2000 50 1000 12 2000 Bridge Configuration VD Vi RL + + - -
