TDA7376PD 2 x 35 W power amplifier for car radio Features ■ High output power capability: – 2 x 40 W max./4  – 2 x 35 W/4  EIAJ – 2 x 25 W/4  @14.4 V, 1 kHz, 10 % – 2 x 25 W/2  @14.4 V, 1 kHz, 10 % PowerSO36 (Slug up) ■ 2  driving ■ Differential inputs ■ Minimum external components count ■ Internally fixed gain (26 dB) ■ Mute function (CMOS compatible) ■ Automute at minimum supply voltage detection ■ Standby function ■ No audible pop during mute and standby operations ■ Clipping detector with programmable distortion threshold ■ Description Protections: – Short circuit (out to ground, out to supply voltage, across the load) – Overrating chip temperature with soft thermal limiter – Load dump voltage – Fortuitous open ground – Loudspeaker DC current – ESD Table 1. The TDA7376PD is a new technology dual bridge audio amplifier in PowerSO36 package designed for car radio applications. Thanks to the fully complementary PNP/NPN output stage configuration the TDA7376PD delivers a rail-to-rail voltage swing with no need of bootstrap capacitors. Differential input pairs, that will accept either single ended or differential input signals, guarantee high noise immunity making the device suitable for both car radio and car boosters applications. The audio mute control, that attenuates the output signal of the audio amplifiers, suppresses pop on - off transients and cuts any noises coming from previous stages. The standby control, that de-biases the amplifiers, reduces the cost of the power switch. The on-board programmable distortion detector allows compression facility whenever the amplifier is overdriven, so limiting the distortion at any levels inside the presettable range.

Electrical specifications Mute pin current Distortion detection level V6 = 0 to VS,; VS max. = 18 V (2) Distortion detector output DC current - 55 dB Saturated square wave output 2. See Figure 3 for THD setting. The TDA7376PD is equipped with a programmable clipping distortion detector circuitry that allows to signal out the output stage saturation by providing a current sinking into an open collector output (DDOUT) when the total harmonic distortion of the output signal reaches the preset level. The desired threshold is fixed through an external divider that produces a proper voltage level across the THD set pin. Figure 3 shows the THD detection threshold versus the THD set voltage. Since it is essential that the THD set voltage be proportional to the supply voltage, Figure 4 shows its value as a fraction of VCC. The actual voltage can be computed by multiplying the fraction corresponding to the desired THD threshold by the application’s supply voltage.
