The LTC2066/LTC2067 are single and dual low power, zero-drift, 100kHz amplifiers. The LTC2066/LTC2067 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’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 allows the use of high value power-saving resistors in the feedback network.
With its ultralow quiescent current and outstanding precision, the LTC2066/LTC2067 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 TSOT23 packages. The LTC2067 is available in 8-lead MSOP and 10-lead DFN packages. These devices are fully specified over the –40°C to 85°C and –40°C to 125°C temperature ranges.
