Operational Amplifier
Description
The LTC®2063 is a single low power, zero-drift, 20kHz
amplifier. The LTC2063 enables high resolution measure-
ment at extremely low power levels.
Typical supply current is 1.4µA with a maximum of 2µA.
The available shutdown mode has been optimized to mini-
mize power consumption in duty-cycled applications and
features low charge loss during power-up, reducing total
system power.
The LTC2063’s self-calibrating circuitry 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 al-
lows the use of high value power-saving resistors in the
feedback network.
With its ultralow quiescent current and outstanding pre-
cision, the LTC2063 can serve as a signal chain building
block in portable, energy harvesting and wireless sensor
applications.
The LTC2063 is available in 6-lead SC70 and 5-lead TSOT-
23 packages and is fully specified over the –40°C to 85°C
and –40°C to 125°C temperature ranges.

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 is guaranteed to meet specified performance
from –40°C to 85°C. The LTC2063H is 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.
VOS is measured to a limit determined by test equipment capability.
Note 7: Minimum specifications for these parameters are limited by noise
and the capabilities of the automated test system.
