Description

The LTC®2066 is a single low power, zero-drift, 100kHz amplifier. The LTC2066 enables high resolution measurement at extremely low power levels.

Typical supply current is 7.5μA 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 power-up, reducing total system power.

The LTC2066’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 LTC2066 allows the use of high value power-saving resistors in the feedback network.

With its ultralow quiescent current and outstanding precision, the LTC2066 can serve as a signal chain building block in portable, energy harvesting and wireless sensor applications.

The LTC2066 is available in 6-lead SC70 and 5-lead TSOT- 23 packages and is fully specified over the –40°C to 85°C and –40°C to 125°C temperature ranges.
