Control signal parameters over recommended operating conditions (unless otherwise noted)
PARAMETER MIN TYP MAX UNIT
t
w(ER)
Pulse duration, BKND_ERR active (active-low) 350 None ns
t
p(valid_high)
Programmable. Time to stay in the OUT_x low state. After t
p(valid_high)
, the TAS5716
attempts to bring the system out of the OUT_x low state if BKND_ERR is high. See ms
register 0x1C.
t
p(valid_low)
Time TAS5716 takes to bring OUT_x low after BKND_ERR assertion. 350 ns

PARAMETER MIN TYP MAX UNIT
t
d(VOL)
Volume ramp time. Ramp time = number of steps (programmable number of steps, see 1024 steps
register 0x0E) × step size
(1)
(1) Stepsize = 4 LRCLKs (for 32 – 48 kHz sample rate); 8 LRCLKs (for 88.2 – 96 kHz sample rate); 16 LRCLKs (for 176.4 – 192 kHz sample
rate)
