Analog Devices Inc. LTC206x Operational Amplifiers

Analog Devices LTC206x Operational Amplifiers are single and dual low-power, zero-drift amplifiers. The LTC2063/LTC2064 are 20kHz amplifiers, and the TC2066/LTC2067 are 100kHz amplifiers. The amplifiers enable high-resolution measurement at extremely low power levels. The LTC2063/LTC2064 has a typical supply current of 1.4µA per amplifier with a maximum of 2µA. The LTC2066/LTC2067 has a typical supply current of 7.5µA per amplifier with a maximum of 10µA. The available shutdown mode has been optimized to minimize power consumption in duty-cycled applications. The devices feature low charge loss during powerup, reducing total system power.
