The Gainsil GS4558-SR is an operational amplifier with SOP-8 package and ROHS certified, which is designed to meet the needs of higher speed operations and reduce power consumption. It utilizes a high speed, low noise, current feedback, single-ended-input design to offer fast settling time and high accuracy performance characteristics. It features -3dB bandwidth up to 40MHz, differential gain/phase < 0.03%, SR < 100V/us, and supply current of 220µA/amplifier. It also has high common mode rejection of 60dB and rail-to-rail analog inputs with a per amplifier PSRR of -69dB. It is suitable for applications such as data acquisition, signal processing, and power supplies.
