The NS4248 is an audio power operational amplifier (OpAmp) in a Small Outline Package (SOP) form. It is manufactured by Nsiway and is RoHS compliant. It is a high quality, low noise OpAmp, designed for audio power applications that require high linearity and low distortion. It has a wide frequency response of 3.3Hz to 124kHz, a gain-of-gain temperature coefficient of 0.00001%, and an output current capability up to 10mA. The NS4248 also has a wide operating voltage range from 3V to 30V and an output power stage of up to 400W. It features a low input bias current of below 5nV/Hz and a guaranteed phase margin of 50°. This makes it ideal for use in high fidelity audio power amplifiers, as well as in electronic musical instruments and speech recognition circuits.
