Hot-selling and scarce SSM2301RMZ Filterless High Efficiency Mono 1.4W Class-D Audio Amplifier MSOP8 spot stock

Product Descriptions

The SSM2301 is a fully integrated, high efficiency, Class-D audioamplifier designed to maximize performance for mobile phoneapplications . The application circuit requires a minimum ofexternal components and operates from a single 2.5 V to 5.0 Vsupply. It is capable of delivering 1.4 W of continuous outputpower with less than 1% THD + N driving an 8 Ω load froma 5.0 V supply.

The SSM2301 features a high efficiency, low noise modulationscheme that does not require external LC output filters .The modulation provides high efficiency even at low output power.

The SSM2301 operates with 85% efficiency at 1.4 W into 8 Ωfrom a 5.0 V supply and has a signal-to-noise ratio (SNR)thatis greater than 98 dB . Spread-spectrum modulation is used toprovide lower EMI-radiated emissions compared with otherClass-D architectures .
