DESCRIPTIO
The LTC
®
2054/LTC2055 are low power, low noise single/
dual zero-drift operational amplifiers available in the SOT-23
(ThinSOT
TM
) and MS8 packages. For space limited appli-
cations, the LTC2055 is also available in a 3mm

3mm
×
0.8mm dual fine pitch leadless package (DFN). They
operate from a single 2.7V minimum supply and support
±5V
applications. The current consumption is typically
150µA for the LTC2054 and 130µA/amp for the LTC2055.
The LTC2054/LTC2055, despite their miniature size, fea-
ture uncompromising DC performance. The typical input
offset voltage 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 rejec-
tion 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/LTC2055
also feature a 1.6µV
P-P
DC to 10Hz noise and a 500kHz
gain-bandwidth product.
