Op Amp Combines Femtoamp Bias Current with 4GHz Gain Bandwidth Product, Shines New Light on Photonics Applications
The LTC6268 Op Amp family delivers accuracy for high gain, high speed transimpedance amplifier and sensor conditioning circuits, with just 3 femtoamperes input bias current at room temperature and 0.9 pA max at 85°C. For photodiode, CCD and other high impedance sensor circuits, this stable low bias current, combined with 4GHz gain-bandwidth product, extremely low input capacitance and low noise provide outstanding performance in a small footprint. The LTC6268-10 is stable with a min gain of 10; a unity gain stable version is also available.
