General Description
The MAX9820 Windows Vista-compliant stereo head-
phone amplifier is designed for portable equipment
where board space is at a premium. It features Maxim’s
DirectDrive architecture to produce a ground-refer-
enced output from a single supply, eliminating the large
output-coupling capacitors required by conventional
single-supply headphone amplifiers.
The MAX9820 features an undervoltage lockout that
prevents over discharging of the battery during
brownout conditions, click-and-pop suppression that
eliminates audible transients on startup, a low-power
shutdown mode, and thermal-overload and short-circuit
protection. Additionally, the MAX9820 suppresses RF
radiation received by input and supply traces acting as
antennas and prevents the amplifier from demodulating
the coupled noise.
The MAX9820 is available in a 10-pin TDFN package
(3mm x 3mm x 0.8mm) and specified over the -40°C to
+85°C extended temperature range.
