LTC2066IS5#TRMPBF

LTC2066 is a single channel, low power, zero-drift, 100KHz amplifier. It enables high resolution measurement at extremely low power levels. This device'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 device allows the use of high value power-saving resistors in the feedback network. It is used in applications such as 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.
