The LTC2068 are quad low power, zero-drift, 100kHz amplifiers. The LTC2068 enable high resolution measurement at extremely low power levels.
Typical supply current is 7.5μA per amplifier with a maximum of 10μA. 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 LTC2068’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 35pA and does not exceed 150pA over the full specified temperature range. The extremely low input bias current of the LTC2068 allows the use of high value power-saving resistors in the feedback network.
With its ultralow quiescent current and outstanding precision, the LTC2068 can serve as a signal chain building block in portable, energy harvesting and wireless sensor applications.
The LTC2068 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.
