The LTC
®
2054 and LTC2054HV are low power, low noise
zero-drift operational amplifiers available in the
5-lead SOT-23 package. The LTC2054 operates from a
single 2.7V to 6V supply. The LTC2054HV operates on
supplies from 2.7V to
±5.5V.
The current consumption is
150µA (typical), 175µA maximum over temperature.
The LTC2054, despite its miniature size, features uncom-
promising DC performance. The typical input offset volt-
age and offset drift are 0.5µV and 25nV/°C. The almost
zero DC offset and drift are supported with a power supply
rejection ratio (PSRR) and common mode rejection ratio
(CMRR) of more than 130dB.
The input common mode voltage ranges from the negative
supply up to typically 0.5V from the positive supply. The
open-loop gain is typically 140dB. The LTC2054 also
features a 1.6µV
P-P
DC to 10Hz noise and a 500kHz gain
bandwidth product.

Note 1:
Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2:
These parameters are guaranteed by design. Thermocouple effects
preclude measurements of these voltage levels during automated testing.
Note 3:
Limit is determined by high speed automated test capability. See
characteristic curves for actual typical performance. For tighter
specifications, please consult Linear Technology Marketing.
Note 4:
The LTC2054C, LTC2054HVC are guaranteed to meet specified
performance from 0°C to 70°C and are designed, characterized and
expected to meet these extended temperature limits, but are not tested at
–40°C and 85°C. The LTC2054I, LTC2054HVI are guaranteed to meet the
specified performance from –40°C and 85°C.
