Note 1: When the MUTE pin is high, the outputs will be on, and when low, the outputs will be off. (In the amplifier output off state, the outputs are in the
high-impedance state.) This operation applies to all channels.
2: The voltage across the load terminals when an 8 load is connected across the outputs. With the input either high or low. With the output in
the saturated state.
3: The channel 1 input operational amplifier has a 0 dB gain, i.e. it is a buffer amplifier.
4: Design guarantee value
5: When V
IN
1-SW is high, operational amplifier A operates, and when low, operational amplifier B operates.
6: For testing, short the REGOUT to the collector of the external pnp transistor.
