Low-Power, Low-Offset, Dual Mode, Class H
DirectDrive Headphone Amplifier MAX97200
19-4981; Rev 3; 8/12
General Description
The MAX97200 is a 45mW Class H headphone amplifier
that runs from a single low 1.8V supply voltage and employs
Maxim’s second-generation DirectDrive technology.
The MAX97200 features a Dual ModeK internal charge
pump to generate the power rails for the amplifier. The
charge-pump output can be QPVIN/2 or QPVIN depend-
ing on the amplitude of the output signal. When the out-
put voltage is low, the power-supply voltage is QPVIN/2.
When the output signal demands larger output voltage,
the charge pump switches modes so that a greater
power-supply voltage is realized and more output power
can be delivered to the load.
Second-generation DirectDrive technology improves
power consumption when compared to first-generation
DirectDrive amplifiers. The MAX97200 can be powered
from a regulated 1.8V and have similar power consump-
tion to a traditional DirectDrive amplifier that is powered
from 0.9V.
Maxim’s DirectDrive architecture uses an inverting
charge pump to derive a negative voltage supply. The
headphone amplifier is powered between the positive
supply and the generated negative rail. This scheme
allows the audio output signal to be biased about
ground, eliminating the need for large DC-blocking
capacitors between the amplifier output and the head-
phone load.
Low-output offset voltage provides very good click-and-
pop performance both into and out of shutdown. High
signal-to-noise ratio maintains system fidelity.
The MAX97200 is available in a tiny, 12-bump wafer
level packaging (WLP 1.27mm x 1.65mm) with a small,
0.4mm lead pitch and specified over the -40NC to +85NC
extended temperature range.
