20 µA Op Amp Provides 30 µV Precision

Linear Technology introduces the LT6023, a dual 3 V to 30 V low power operational amplifier, featuring 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.

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 480µs 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. Fully specified over the -40°C to 85°C and -40°C to 125°C temperature ranges, the LT6023 is available in MSOP-8 and 3x3mm DFN packages.
