MAX98357AEWL+T

MAX98357AEWL+T is a tiny, low-cost, PCM class D amplifier with class AB performance. It provides industry-leading Class AB audio performance with class D efficiency. The digital audio interface automatically recognizes up to 35 different PCM and TDM clocking schemes which eliminates the need for I2C programming. Operation is further simplified by eliminating the need for an external MCLK signal that is typically used for PCM communication. Simply supply power, LRCLK, BCLK, and digital audio to generate audio. It supports 8 channel time division multiplexed (TDM) data. The digital audio interface accepts specified sample rates between 8KHz and 96KHz for all supported data formats. The IC also features a very high wideband jitter tolerance (12ns typ) on BCLK and LRCLK to provide robust operation. Applications include single li-ion cell/5V devices, smart speakers, notebook computers, IoT devices, gaming devices (audio and haptics), smartphones, tablets, cameras.

• No MCLK required, extensive click-and-pop reduction circuitry
• Sophisticated edge rate control enables filterless class D outputs
• Low RF susceptibility rejects TDMA noise from GSM radios
• Robust short-circuit and thermal protection, solution size with single bypass capacitor is 4.32mm2
• Supply voltage range from 2.5 to 5.5V
• Quiescent current is 2.75mA at TA=+25°C
• Output offset voltage is ±0.3mV at TA=+25°C, gain=15dB
• Power-supply rejection ratio is 77dB at f=217Hz, 200mVP-P ripple, TA=+25°C
• 9 WLP package
• Temperature range from -40°C to +85°C
