Quad Audio Line Driver with 3VRMS Output

Note 1: All devices are 100% tested at TA = +25°C. Specifications over temperature are guaranteed by design.
Note 2: Inputs AC-coupled to PGND.
Note 3: Click-and-pop testing performed with a 1k resistive load connected to ground. Mode transitions are controlled by SHDN.
KCP level is calculated as 20log[(peak voltage during mode transition, no input signal)/1VRMS]. Units are expressed in dBV.
ELECTRICAL CHARACTERISTICS
(VDD = PVDD = 3.3V, PGND = 0V, SHDN = VDD, VCM = 0V, C1 = C2 = 1F, RIN = RF = 5k, RL = ∞, TA = TMIN to TMAX. Typical val-
ues are at TA = +25°C.) (Note 1)
