LTC2068IF#PBF

LTC2068 is quad low power zero-drift 100KHz operational amplifier. It enable high resolution measurement at extremely low power levels. The 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. The maximum input bias current is only 35pA and does not exceed 150pA over the full specified temperature range. The 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. • Self-calibrating circuitry results in very low input offset 5µV maximum and offset drift 0.02µV/°C• Typical supply current is 7.5µA per amplifier with a maximum of 10µA• Offset voltage drift of 0.02µV/°C maximum• Input bias current of 5pA typical• Integrated EMI filter (90dB rejection at 1.8GHz)• Shutdown current of 170nA maximum (per amplifier)• Rail-to-Rail input and output• 1.7V to 5.25V operating supply range• Low-charge power-up for duty cycled applications• 14-lead TSSOP package, -40°C to 85°C range
