MAX98390 Overview
Description
The MAX98390 is a high-efficiency mono Class-D DSM smart amplifier that features an integrated boost converter, integrated Dynamic Speaker ManagementTM, and FET scaling for higher-efficiency at low output power. The maximum boost converter output voltage is programmable from 6.5V to 10V in 0.125V increments from a battery voltage as low as 2.65V.
Key Features
- an integrated boost converter, integrated Dynamic Speaker ManagementTM, and FET scaling for higher-efficiency at low output power
- The maximum boost converter output voltage is programmable from 6.5V to 10V in 0.125V increments from a battery voltage as low as 2.65V
- The boosted supply efficiently delivers up to 6.2W at 10% THD+N into a 4Ω load
- The PCM interface supports I2S, left-justified, and 16-channel TDM formats as a slave or master device with I2C control
- Either BCLK or MCLK can be used as the internal clock source providing system level flexibility
- Thermal and other status data can also be read from the I2C interface
- Threshold, hysteresis, and attack-and-release rates are programmable
- The MAX98390C is available in a 0.4mm pitch, 36-bump wafer-level package
- The MAX98390D is available in a 0.5mm pitch, 30-bump wafer-level package
- They are specified over the extended -40°C to +85°C temperature range
