The LTC2063/LTC2064/LTC2065 enable high resolution measurement at extremely low power levels. Typical supply current is 1.4µA per amplifier with a maximum of 2µA. 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 LTC2063/LTC2064/LTC2065’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 20p A and does not exceed 100p A over the full specified temperature range. The extremely low input bias current of the LTC2063/LTC2064/LTC2065 allows the use of high value power-saving resistors in the feedback network. With its ultralow quiescent current and outstanding precision, the LTC2063/LTC2064/LTC2065 can serve as a signal chain building block in portable, energy harvesting and wireless sensor applications.
