5V, Differential Input, DirectDrive, 130mW

Stereo Headphone Amplifiers with Shutdown

ELECTRICAL CHARACTERISTICS (continued)

(PVDD = SVDD = +5V, PGND = SGND = 0V, SHDN = SVDD, C1 = C2 = 1µF, RL = ∞, resistive load referenced to ground, for

MAX9722A gain = -1V/V (RIN = RF = 10kΩ), for MAX9722B gain = -2V/V (internally set), TA = -40°C to +85°C, unless otherwise noted.

Typical values are at TA = +25°C, unless otherwise noted.) (Note 1)

Note 1: All specifications are 100% tested at TA = +25°C; temperature limits are guaranteed by design.

Note 2: Gain for the MAX9722A is adjustable.

Note 3: The amplifier inputs are AC-coupled to ground through CIN_.

Note 4: Measurement bandwidth is 22Hz to 22kHz.
