20-µA Op-Amp for 30-µV Precision

Linear Technology’s LT6023 is a dual 3-to-30-V low-power operational amplifier that features 30-µV maximum input offset voltage and 60 µs settling to 0.01%. Proprietary slew enhancement circuitry results in a fast, clean output step response with low power consumption. Specially designed input circuitry maintains high impedance, which minimizes current spikes associated with fast steps for input steps up to 5 V. Together these features make the LT6023 an ideal for portable high-precision instruments, multiplexed data acquisition systems, and DAC buffer applications.Linear LT6023

The LT6023-1 includes a shutdown mode, which reduces the supply current to less than 3 µA when the amplifier is not active. Enable time of 480 µs and fast slew rate combine to provide power-efficient operation in duty-cycled applications, such as those featuring Linear Technology’s Dust Networks wireless sensor network products.
