... Philips Semiconductors 8. Functional description The TDA8942P is a stereo BTL audio power amplifier capable of delivering 2 output power gain is fixed at 32 dB. With the three-level MODE input the device can be switched from ‘standby’ to ‘mute’ and to ‘operating’ mode. The TDA8942P outputs are protected by an internal thermal shutdown protection mechanism and a short-circuit protection. 8.1 Input confi ...

... For the average listening level a power dissipation of 1.15 W can be used for calculation of the maximum ambient temperature T 8.3 Mode selection The TDA8942P has three functional modes, which can be selected by applying the proper DC voltage to pin MODE. See which depend on the supply voltage level. The MODE pin can be driven by a 3-state logic output stage: e ...

... A larger capacitor value on the SVR pin improves the ripple rejection behaviour at the lower frequencies. 8.5 Built-in protection circuits The TDA8942P contains two types of protection circuits, i.e. short-circuit and thermal shutdown. 8.5.1 Short-circuit protection Short-circuit to ground or supply line — This is detected by a so-called ‘missing current’ ...
