Function:
cles in Single Speed, 2304 cycles in Double Speed and 4608 cycles in Quad Speed mode. The bias volt-
age on the outputs will be retained and MUTEC will go active at the completion of the ramp period.
The analog outputs will ramp to a normal state when this function transitions from the enabled to disabled
state. The ramp requires 1152 left/right clock cycles in Single Speed, 2304 cycles in Double Speed and
4608 cycles in Quad Speed mode. The MUTEC will release immediately on setting MUTE = 1.
The converter analog outputs will mute when enabled. The bias voltage on the outputs will be retained
and MUTEC will go active during the mute period.
Determines if the device will operate in either the Hardware Mode or Control Port Mode.
The Mute Control pin goes low during power-up initialization, reset, muting, master clock to left/right clock
frequency ratio is incorrect or power-down. This pin is intended to be used as a control for an external mute
circuit to prevent the clicks and pops that can occur in any single supply system. Use of Mute Control is not
mandatory but recommended for designs requiring the absolute minimum in extraneous clicks and pops.
Analog ground reference.
The full scale differential analog output level is specified in the Analog Characteristics specifications table.
Power for the analog and reference circuits. Typically 5VDC.
