Analog Devices / Maxim Integrated MAX98309/MAX98310 Mono 1.4W Class AB Audio Amps

Analog Devices MAX98309 / MAX98310 Mono 1.4W Class AB Audio Amplifiers offer low quiescent current while maintaining excellent SNR and low 0.008% THD+N. The amplifiers feature excellent 90dB PSRR and state-of-the-art click-and-pop suppression. These ICs are offered with an internally fixed 0dB, 3dB, 6dB, and 9dB gain (MAX98310) or an externally set gain (MAX98309) through external resistors. MAX98309 features a 10ms or 100ms pin-selectable turn-on time, while the MAX98310 has a preset 5ms turn-on time. Analog Devices MAX98309 / MAX98310 Class AB Audio Amplifiers are ideal for use in cell phones/smartphones, digital cameras, e-Readers, and more. The MAX98309 evaluation kit (EV kit) is a fully assembled and tested circuit board that evaluates the MAX98309 and MAX98310. The EV kit operates from a single 2.5V to 5.5V power supply.
