Note 1: All specifications are 100% tested at TA = +25°C; temperature limits are guaranteed by design.
Note 2: Input leakage current measurements limited by automated test equipment.
Note 3: fIN = 1kHz, TA = +25°C, THD+N < 1%, both channels driven in-phase.
Note 4: Testing performed with 32
Ω resistive load connected to outputs. Mode transitions controlled by SHDN. KCP level calculated
as 20 log [peak voltage under normal operation at rated power level / peak voltage during mode transition]. Inputs are AC-
grounded.
Note 5: Using existing resistors with 1% precision.
Note 6: RIN = 10Ω, RF =10kΩ.
Typical Operating Characteristics
(VDD = 1.5V, VPGND = VSGND = 0V, VSHDN = 1.5V, VSS = VPVSS, C1 = C2 = 1F, CIN = 1F, THD+N measurement bandwidth =
22Hz to 22kHz, TA = +25
°C, unless otherwise noted.) (See the Functional Diagrams.)
