Rev. CFor more information www.analog.com Document Feedback TYPICAL APPLICATION FEATURES DESCRIPTION 2µA Supply Current, Low IB, Zero-Drift Operational Amplifiers The LT C®2063/LTC2064/ LTC2065 are single, dual, and quad low power , zero-drift, 20kHz amplifiers. The LTC2063/LTC2064/LTC2065 enable high resolution mea- surement at extremely low power levels. Typical supply current is 1.4µA per amplifier with a max- imum of 2µA. The available shutdown mode has been optimized to minimize power consumption in duty-cycled applications and features low charge loss during pow - er-up, reducing total system power . The LTC2063/ LTC2064/LTC2065’s self-calibrating cir - cuitry results in very low input offset (5µV max) and offset drift (0.02µV/°C). The maximum input bias current is only 20pA and does not exceed 100pA over the full specified temperature range. The extremely low input bias current of the LTC2063/LTC2064/LTC2065 allows the use of high value power-saving resistors in the feedback network. With its ultralow quiescent current and outstanding pre - cision, the LTC2063/ LTC2064/LTC2065 can serve as a signal chain building block in portable, energy harvest - ing and wireless sensor applications. The LTC2063 is available in 6-lead SC70 and 5-lead TSOT-23 packages. The LTC2064 is available in 8-lead MSOP and 10-lead DFN packages. The LTC2065 is avail- able in 14-lead TSSOP and 16-lead 3mm × 3mm QFN packages. These devices are fully specified over the –40°C to 85°C and –40°C to 125°C temperature ranges.

Unless otherwise noted, VS = 5V, VCM = VOUT = VS/2, VSHDN = 5V, RL to VS/2. Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: The inputs are protected by two series connected ESD protection diodes to each power supply. The input current should be limited to less than 10mA. The input voltage should not exceed 300mV beyond the power supply. Note 3: A heat sink may be required to keep the junction temperature below the absolute maximum rating when the output is shorted indefinitely. Note 4: The LTC2063I/LTC2064I/LTC2065I are guaranteed to meet specified performance from –40°C to 85°C. The LTC2063H/LTC2064H/ LTC2065H are guaranteed to meet specified performance from –40°C to 125°C. Note 5: Thermal resistance varies with the amount of PC board metal connected to the package. The specified values are for short traces connected to the leads. Note 6: These parameters are guaranteed by design. Thermocouple effects preclude measurements of these voltage levels during automated testing. V OS is measured to a limit determined by test equipment capability. Note 7: Input bias current is only production tested at 5V. Input bias current at 1.8V is expected to meet or exceed 5V specifications. Note 8: Minimum specifications for these parameters are limited by noise and the capabilities of the automated test system.
