MAX5456/MAX5457
Balance Control
In balance-control mode, the MAX5456/MAX5457
adjust the balance between channel 0 and channel 1
while maintaining the set volume. For example, if the
volume of channel 0 equals the volume of channel 1,
forcing the balance towards channel 1 increases the
attenuation of channel 0 (Figure 4a). If channel 1 is at a
higher attenuation than channel 0, adjusting the bal-
ance to channel 1 moves channel 1’s wiper up to the
same wiper position as channel 0 before attenuating
channel 0 (Figure 4b).
To control the wiper quickly with a logic signal, main-
tain pulses at least 22.5ms wide and separated by at
least 40ms.
