Note 1. MUTEN = HIGH, PDWN = HIGH, input and VREF1 connected by 600Ω, DRCN = HIGH, no-load output
Note 2. MUTEN = LOW, PDWN = LOW, input and VREF1 connected by 600Ω, DRCN = HIGH, no-load output
Note. The usage with direct coupling to load is recommended for operating VDD1, VDD2, VDD3 and VDD4 at ≤ 2.4V. When using LC-type LPF, the
ringing phenomena due to rush current may be judged as short-circuit of the load. In this case, the normal operation will start after the mute for 5
seconds.
