DESCRIPTIO
EATURE
S
F
The LTC®2050 is a low drift operational amplifier available
in the 5- or 6-lead SOT-23 and SO-8 packages. It operates
from a single 2.7V supply while still supporting 5V appli-
cations. The power consumption is 800µA and the ver-
sionsinthe6-leadSOT-23andSO-8packagesofferpower
shutdown (active low).

SOT-23 Package
Maximum Offset Voltage of 3µV
Maximum Offset Voltage Drift of 30nV/°C
Noise: 1.5µVP-P (0.1Hz to 10Hz Typ)
Voltage Gain: 140dB (Typ)
PSRR: 130dB (Typ)
CMRR: 130dB (Typ)
The LTC2050, despite its miniature size, features uncom-
promising DC performance. The typical input offset volt-
age and offset drift are 0.5µV and 10nV/°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.
Supply Current: 0.8mA (Typ)
Single Supply Operation: 2.7V to 6V
Extended Common Mode Input Range
Output Swings Rail-to-Rail
Overload Recovery Time: 2ms (Typ)

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: The LTC2050C is guaranteed to meet specified performance from
0°C to 70°C and is designed, characterized and expected to meet these
extended temperature limits, but is not tested at –40°C and 85°C. The
LTC2050I is guaranteed to meet the extended temperature limits.
