TDA2040 25-watt hi-fi audio power amplifier Datasheet production data Features Wide-range supply voltage, up to 40 V Single or split power supply Short-circuit protection to ground Thermal shutdown P = 25 W THD = 0.5%, V = 17 V, R = 4 O S L Pentawatt V P = 30 W THD =10%, V = 17 V, R = 4 O S L comprising an arrangement for automatically limiting the dissipated power so as to keep the Description operating point of the output transistors within their safe operating range. A thermal shutdown The TDA2040 is a monolithic integrated circuit in system is also included. the Pentawatt package, intended for use as an audio class-AB amplifier. Typically, it provides Table 1. Device summary 25 W output power into 4 with THD = 0.5% at V = 34 V. The TDA2040 provides high output S Order code Package current and has very low harmonic and crossover distortion. Furthermore, the device incorporates a TDA2040V Pentawatt V (vertical) patented short-circuit protection system Figure 1.
