LT1457CN8#PBF

LT1457 is a dual, precision JFET input op-amp. It is optimized for handling large capacitive loads in combination with precision performance. Precision specifications include 220µV offset voltage in plastic and surface mount packages. At 70°C input bias current is 50pA, input offset current is 20pA. Channel separation is 130dB. Typical applications are sample-and-hold (drives large hold capacitors), A/D and D/A converters, photodiode amplifiers, voltage-to-frequency converters.
