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.
