Linear Technology introduces the LT6020, a dual 3V to 30V fast settling operational amplifier, featuring 30μV maximum input offset voltage and 0.5μV/°C max VOSdrift. While supply current is only 100μA maximum per amplifier, proprietary slew enhancement circuitry provides fast clean output step response.
The LT6020 settles to 0.0015% in less than 15μs regardless of whether the output step is 5V or 25V. Specially designed input circuitry maintains high impedance, inimizing current spikes associated with fast steps for input steps up to 5V.
Together these features make the LT6020 ideal for high precision multiplexed data acquisition systems, DAC buffer applications, and portable high precision instruments.The LT6020-1 includes a shutdown mode, reducing the supply current to less than 3μA when the amplifier is in active. Enable time of 100μs 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 technology.
Fully specified over the -40°C to 85°C and -40°C to 125°C temperature ranges, the LT6020 is available in MSOP-8 and 3mm x 3mm DFN packages. Prices start at $1.85 each in quantities of 1,000 units.
