LTC6269IDD-10#PBF

LTC6269-10 is a dual 4GHz ultra-low bias current FET input op-amp with extremely low input bias current and low input capacitance. It also features low input-referred current noise and voltage noise making it an ideal choice for high speed transimpedance amplifiers, and high-impedance sensor amplifiers. It is a decompensated op-amp that is gain-of-10 stable. A shutdown feature can be used to lower power consumption when the amplifier is not in use. Applications include transimpedance amplifiers, ADC drivers, photomultiplier tube post-amplifier, low IBIAS circuits.
