LT6234IDD#PBF

LT6234 is a single, low noise, rail-to-rail output unity-gain stable op amp. This amplifier combines very low noise and supply current with a 60MHz gain bandwidth product, a slew rate and is optimized for low supply voltage signal conditioning systems. The amplifier family has an output that swings within 50mV of either supply rail to maximize the signal dynamic range in low supply applications. Typical applications are ultrasound amplifiers, low noise, low power signal processing, active filters, driving A/D converters, rail-to-rail buffer amplifiers.
