Low-Power, Low-Offset, Dual Mode, Class H  
DirectDrive Headphone Amplifier  
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 DirectDrivetechnology.  
Features  
S Second-Generation DirectDrive Technology  
S Dynamic, Class H, Dual Mode Charge Pump  
S Low Voltage Operation, V = 1.8V  
PVIN  
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.

S Eliminates Large Output DC-Blocking Capacitors  
S Industry-Leading Click-and-Pop Performance  
S High-Fidelity, SNR 105dB (5.6µV Output Noise)  
S Output Power 34mW into 32I (THD+N 1%)  
S Output Power 45mW into 16I (THD+N 10%)  
S Tiny, 12-Bump, 1.27mm x 1.65mm (0.4mm Lead  
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.

PART  
Maxim’s patented 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 headphone load.

Note: All devices operate over the -40°C to +85°C tempera-  
ture range.  
+Denotes a lead(Pb)-free and RoHS-compliant package.  
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.  
Typical Operating Circuit  
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.
