Philips Semiconductors Product specification
2 W BTL audio amplifier TDA8543
DC CHARACTERISTICS
VCC =5V; T
amb =25°C; RL=8Ω; VMODE = 0 V; G = 20 dB; measured in test circuit Fig.4; unless otherwise specified.
Notes
1. With a load connected at the outputs the quiescent current will increase, the maximum of this increase being equal
to the DC output offset voltage divided by RL.
2. The DC output voltage with respect to ground is approximately 0.5 ×VCC.
AC CHARACTERISTICS
VCC =5V; T
amb =25°C; RL=8Ω; f = 1 kHz; VMODE = 0 V; G = 20 dB; measured in test circuit Fig.4; unless otherwise
specified.
