LTC2068x Operational Amplifiers

Analog Devices Inc. LTC2068x Operational Amplifiers are designed for high-resolution measurements at low power levels. These amplifiers operate within a 1.7V to 5.25V operating voltage range and 10µA maximum supply current. The LTC2068x amplifiers' self-calibrating circuitry provides 5µV low input offset (maximum) and 0.02µV/°C offset drift. The shutdown mode is optimized to minimize power consumption in duty-cycled applications and features low charge loss during power-up that reduces total system power. These amplifiers provide a low input bias current that allows for the use of high-value power-saving resistors in the feedback network. The LTC2068x amplifiers are available in 14-lead TSSOP and 16-lead 3mm × 3mm QFN packages.
