The LTC2066/LTC2067/LTC2068 are single, dual, and quad low power, zero-drift, 100kHz amplifiers. The LTC2066/LTC2067/LTC2068 enable high resolution measurement at extremely low power levels. Typical supply current is 7.5μA per amplifier with a maximum of 10μA. The available shutdown mode has been optimized to minimize power consumption in duty-cycled applications and features low charge loss during powerup, reducing total system power. The LTC2066/LTC2067/LTC2068’s self-calibrating circuitry 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 precision, the LTC2066/LTC2067/LTC2068 can serve as a signal chain building block in portable, energy harvesting 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.
