Linear Technology/Analog Devices’ LTC6240, LTC6241, and LTC6242 devices are single, dual, and quad low noise, low offset, rail-to-rail output CMOS operational amplifiers (op amps). Input bias current is guaranteed to be 1 pA max on the single LTC6240. The 0.1 Hz to 10 Hz noise of only 550 nVPP, along with an offset of just 125 μV are significant improvements over traditional CMOS op amps. Additionally, noise is guaranteed to be less than 10 nV/√Hz at 1 kHz. An 18 MHz gain bandwidth, and 10 V/μs slew rate, along with the wide supply range and low input capacitance, make them perfect for use as fast signal processing amplifiers. These op amps have an output stage that swings within 30 mV 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 V and 5 V, and an HV version guarantees operation on supplies up to ±5 V. The LTC6240, LTC6241, and LTC6242 are ideal for precision applications such as medical and test and measurement.
