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 Mode™ internal charge pump to generate the power rails for the amplifier. The charge-pump output can be ±PVIN/2 or ±PVIN depending on the amplitude of the output signal. When the output voltage is low, the power-supply voltage is ±PVIN/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 poweredfrom a regulated 1.8V and have similar power consumption 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 betweenthe positive supply and the generated negative rail. This scheme allows the audio output signal to be biased about ground, eliminating the need for largeDC-blocking capacitors between the amplifier output and the headphone 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 -40°C to +85°C extended temperature range.
