1 / 30 page  LTC2066/LTC2067/LTC2068 1 Rev. B For more information www.analog.com Document Feedback TYPICAL APPLICATION FEATURES DESCRIPTION 10µA Supply Current, Low IB, Zero-Drift Operational Amplifier The LTC®2066/LTC2067/LTC2068 are single, dual, and quad low power, zero-drift, 100kHz amplifiers. The LTC2066/LTC2067/LTC2068 enable high resolution mea- surement at extremely low power levels. Typical supply current is 7.5µA per amplifier with a maxi- mum of 10µA. The available shutdown mode has been optimized to minimize power consumption in duty-cycled applications and features low charge loss during power- up, reducing total system power. The LTC2066/LTC2067/LTC2068’s self-calibrating cir- cuitry results in very low input offset (5µV max) and offset drift (0.02µV/°C). The maximum input bias current is only 35pA and does not exceed 150pA over the full specified temperature range. The extremely low input bias current of the LTC2066/LTC2067/LTC2068 allows the use of high value power-saving resistors in the feedback network. With its ultralow quiescent current and outstanding pre- cision, the LTC2066/LTC2067/LTC2068 can serve as a signal chain building block in portable, energy harvest- ing and wireless sensor applications. The LTC2066 is available in 6-lead SC70 and 5-lead TSOT- 23 packages. The LTC2067 is available in 8-lead MSOP and 10-lead DFN packages. The LTC2068 is available in 14-lead TSSOP and 16-lead 3mm × 3mm QFN packages. These devices are fully specified over the –40°C to 85°C and –40°C to 125°C temperature ranges.
