Analog Devices Inc. LTC2065 Zero-Drift Operational Amplifiers
Analog Devices Inc. LTC2065 Zero-Drift Operational Amplifiers (Op-amps) enable high resolution measurement at extremely low power levels. These zero-drift op-amps are 20kHz amplifiers that offer 2µA supply current and low bias current with low power. The LTC2065 zero-drift operational amplifiers provide low input bias current that allows the use of high value power-saving resistors in the feedback network. These zero-drift op-amps operate at 1.7V to 5.25V input supply voltage range. The LTC2065 zero-drift op-amps are available in 14-lead TSSOP and 16-lead 3mm x 3mm QFN packages. Applications include signal conditioning in wireless mesh networks, portable instrumentation systems, low-power sensor conditioning, gas detection, temperature measurement, medical instrumentation, and energy harvesting applications.Features
