The LTC2063/LTC2064/LTC2065 are single, dual, and quad low power, zero-drift, 20kHz amplifiers. 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 20pA and does not exceed 100pA 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. The LTC2063 is available in 6-lead SC70 and 5-lead TSOT-23 packages. The LTC2064 is available in 8-lead MSOP and 10-lead DFN packages. The LTC2065 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.
