The MAX98925 is a high-efficiency mono Class DG audio amplifier featuring an integrated boost converter and ADCs for sensing speaker current, speaker voltage, and battery supply voltage. The boost converter output voltage is programmable from 6.5V to 8.5V in 0.25V increments from a battery voltage as low as 2.5V. The boosted supply efficiently delivers up to 6.5W at 10% THD+N into a 4Ω load. The boost switching frequency of 2.3MHz allows a small case size 1μH external inductor to be used. The Class DG multilevel amplifier can be supplied externally, bypassing the boost converter and removing the need for an external inductor. With an 8.5V external sup- ply, the IC is up to 87% efficient outputting 3.5W into an 8Ω load. The MAX98925 digital audio interface (DAI) supports I2S, left-justified, and 8-channel TDM formats and can act as master or slave. Either BCLK or MCLK can be used as the internal clock source providing system level flexibility. The speaker current and voltage sense ADCs have 16- bit resolution. Speaker current/voltage sense and bat- tery/boost sense are output from the DAI at the sample rate defined by LRCLK. Battery and boost supply data can also be read from the I2C interface. Active emissions limiting edge rate and overshoot control circuitry, together with Class DG multilevel modulation, minimize EMI and eliminate the need for output filtering found in traditional Class D devices. Automatic level control (ALC) reduces amplifier gain as the battery voltage drops to prevent system reset due to battery collapse. Threshold, maximum attenuation, and attack/release rates are programmable. The IC is available in a 0.5mm pitch 30-bump WLP pack- age. It is specified over the extended, -40°C to +85°C temperature range.
