5 / 19 page 5 Maxim Integrated Differential Input DirectDrive Line Drivers/Headphone Amplifiers MAX97220A–MAX97220E Note 2: 100% production tested at TA = +25NC. Specifications over temperature limits are guaranteed by design. Note 3: Dynamic specifications are taken over 2.5V to 5.5V supply range. Inputs AC-coupled to PGND. Note 4: The maximum differential input signal does not cause any excess distortion due to violation of the common-mode input range. Note 5: Test performed with a resistive load connected to PGND. Mode transitions are controlled by SHDN. KCP level is calcu- lated as 20 x log (peak voltage during mode transition, no input signal). Typical Operating Characteristics (VPVDD = VSVDD = VSVDD2 = 5V, VPGND = VSGND = 0V, CBIAS = 0.1µF, C1 = C2 = 1µF, RIN = 10kω, RF = 10kω, unless otherwise noted.) ELECTRICAL CHARACTERISTICS (continued) (VPVDD = VSVDD = VSVDD2 = 5V, VPGND = VSGND = 0V, CBIAS = 0.1µF, C1 = C2 = 1µF, RIN = 20kω, RF = 20kω (MAX97220A/ MAX97220B/MAX97220E), typical values tested at TA = +25°C, unless otherwise noted.)
