DESCRIPTION
The LTC®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.
