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 off...
