4 / 9 page July 1994 4 Philips Semiconductors Product specification Low voltage mono/stereo power amplifier TDA7050T CHARACTERISTICS VP = 3 V; f = 1 kHz; RL = 32 Ω; Tamb = 25 °C; unless otherwise specified * Output power is measured directly at the output pins of the IC. It is shown as a function of the supply voltage in Fig.2 (BTL application) and Fig.3 (stereo application). PARAMETER SYMBOL MIN. TYP. MAX.
