The LTC6268-10 is a single 4GHz FET input op amp for high dynamic range and high speed transimpedance amplifier (TIA) applications. This new decompensated amplifiers extend the speed and dynamic range capabilities of this ultralow bias current op amp family for applications with a gain of 10 or higher. Input bias current is 0.9pA max over the 40°C to 85°C temperature range and just 4pA max over the entire 40°C to 125°C temperature range.
Wideband voltage and current noise are 4nV/√Hz and 7fA/√Hz, respectively. With 0.45pF input capacitance and 1000V/μs slew rate, the LTC6268-10 is well suited for photodiode and photomultiplier (PMT) circuits, high impedance sensor applications and for driving analog to digital converters (ADCs). The part is also available as a dual op amp (LTC6269-10) and in unity gain stable options (single LTC6268 and dual LTC6269).
