The LTC6241/LTC6242 are dual and quad low noise, low offset, rail-to-rail output, unity gain stable CMOS op amps that feature 1pA of input bias current. The 0.1Hz to 10Hz noise of only 550nVP-P, along with an offset of just 125V make them uncommon among traditional CMOS op amps. Additionally, noise is guaranteed to be less than 10nV/Hz at 1kHz. An 18MHz gain bandwidth, and 10V/s slew rate, along with the wide supply range and low input capacitance, make them perfect for use as fast signal processing amplifiers.
