LTC2064IDD#PBF

LTC2064 is a dual low power, zero-drift, 20KHz amplifier. The LTC2064 enables 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 LTC2064 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 LTC2064 allows the use of high value power-saving resistors in the feedback network. With its ultralow quiescent current and outstanding precision, the LTC2064 can serve as a signal chain building block in portable, energy harvesting and wireless sensor applications.
