LTC2063HSC6#TRMPBF

LTC2063 is a single, low power, zero-drift, 20KHz 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 (±0.03μV/°C). The maximum input bias current is only 0.5pA and does not exceed 100pA 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. With its ultralow quiescent current and outstanding precision, this device can serve as a signal chain building block in portable, energy harvesting and wireless sensor applications. 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.
