ELECTRICAL CHARACTERISTICS (continued)
(VDD = 5V, PGND = SGND, SHDN = 5V, C1 = C2 = 1F, RL = ∞, resistive load reference to ground; for MAX9724C gain = -1.5V/V
(RIN = 20kΩ, RF = 30kΩ); for MAX9724D gain = -1.5V/V (internally set), TA = -40°C to +85°C, unless otherwise noted. Typical values
are at TA = +25°C, unless otherwise noted.) (Note 3)

Note 3: All specifications are 100% tested at TA = +25°C; temperature limits are guaranteed by design.
Note 4: The amplifier inputs are AC-coupled to GND.
Note 5: Gain for the MAX9724C is adjustable.
Note 6: Measurement bandwidth is 22Hz to 22kHz.
Note 7: Test performed with a 32
Ω resistive load connected to GND. Mode transitions are controlled by SHDN. KCP level is calculated
as 20log[(peak voltage during mode transition, no input signal)/(peak voltage under normal operation at rated power level)].
Units are expressed in dB.
