The LTC6244 is a dual high speed, unity-gain stable CMOS op amp that features a 50MHz gain bandwidth, 40V/s slew rate, 1pA of input bias current, low input capacitance and rail-to-rail output swing. The 0.1Hz to 10Hz noise is just 1.5VP-P and 1kHz noise is guaranteed to be less than 12nV/Hz. This excellent AC and noise performance is combined with wide supply range operation, a maximum offset voltage of just 100V and drift of only 2.5V/C, making it suitable for use in many fast signal processing applications, such as photodiode amplifiers.
