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.) (Notes 2 and 3)
