The LTC2063ISC6#TRMPBF from Linear Technology is a single 2μA supply current, low IB, zero-drift operational amplifier in 5 pin SC70 package. This operational amplifier enables 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 power-up, reducing total system power. The extremely low input bias current of the LTC2063 allows the use of high value power-saving resistors in the feedback network. With its ultralow quiescent current and outstanding precision, the LTC2063 can serve as a signal chain building block in portable, energy harvesting and wireless sensor applications. Typical applications include signal conditioning in wireless mesh networks, portable instrumentation systems, low-power sensor conditioning, gas detection, temperature measurement, medical instrumentation and low power current sensing.
