× 0.7 W BTL audio amplifier with
output channel switching
TDA8547TS
DC CHARACTERISTICS
VCC =5V; Tamb =25 °C; RL =8 Ω; VMODE = 0 V; gain = 20 dB; measured in BTL application circuit Fig.4; unless
otherwise specified.
Notes
1. Measured with RL = ∞. 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 0.5VCC.
