LTC2067IDD#PBF

LTC2067 is dual low power zero-drift 100KHz operational amplifier. It enable high resolution measurement at extremely low power levels. Hence 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. Its extremely low input bias current of this allows the use of high value power-saving resistors in the feedback network. With its ultralow quiescent current and outstanding precision, this can serve as a signal chain building block in portable, energy harvesting and wireless sensor applications. Typical applications are signal conditioning in wireless mesh networks, portable instrumentation systems, low-power sensor conditioning, gas detection, temperature measurement, medical instrumentation, energy harvesting applications, low power current sensing. Low-charge power-up for duty cycled applications.
