LV3329PE
No.A1856-27/30
T = -Ct × (R1 + Rt) × 1n
Vs - Vcrt
Vs × ( 1 -
Rt
R1 + Rt
)
[1]
Calculation example)
VDD = 8V, Vs = 4V
Vctr = 1.75V
R1 = 930kΩ (TIM pin internal resistance)
Ct = 0.022μF (External Ct)
Rt = 150kΩ (External Rt)
The timer time “T” is obtained by formula [1] above.
In this example, T = 10.1ms.
(5) Bass/mid-range block soft step operation
The LV3329PE has a soft step function at bass and mid-range blocks to minimize switching noise.
The soft step time for the bass and mid-range blocks is 10ms or 20ms and can be selected using serial data.
When set to soft step on, a soft step function for the bass or mid-range block can be implemented at the minimum
resolution step intervals.
(6) Soft mute operation
The LV3329PE have a soft mute function for low switching noise, when this mute function set operation.
(mute/unmute function select)
The Soft mute time can be selected by send to CCB control. (0.6ms, 5ms, 40ms, 80ms)
A soft mute function can be implemented by set to soft mute on. (Set to mute on/off)
