The LTC6242IGN#PBF is a quad low noise/offset rail-to-rail output unity gain stable CMOS Operational Amplifier that feature 1pA of input bias current. Input bias current is guaranteed to be 1pA maximum on the single LTC6240. The 0.1 to 10Hz noise of only 550nVP-P, along with an offset of just 125μV is significant improvements over traditional CMOS op amps. Additionally, noise is guaranteed to be less than 10nV/√Hz at 1kHz. An 18MHz gain bandwidth and 10V/μs slew rate, along with the wide supply range and low input capacitance, make them perfect for use as fast signal processing amplifiers. The op amp has an output stage that swings within 30mV of either supply rail to maximize the signal dynamic range in low supply applications. The input common mode range extends to the negative supply. They are fully specified on 3 and 5V and an HV version guarantees operation on supplies up to ±5V.
