DESCRIPTION
Single/Dual Micropower
Zero-Drift Operational Ampliers
The LTC2054/LTC2055 are low power, low noise, single/
dual, zero-drift operational ampliers with an extended
temperature version (LTC2054MP) that has guaranteed
specications from –55°C to 150°C. They are available
in TSOT-23 (ThinSOT) and MS8 packages. For space
limited applications, the LTC2055 is also available in a
3mm × 3mm × 0.8mm dual ne 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, feature
uncompromising DC performance. The maximum input
offset voltage and offset drift are 3.0μV and 30nV/°C over
the –40°C to 85°C industrial temperature range. The almost
zero DC offset and drift are supported with a power supply
rejection ratio (PSRR) and common mode rejection ratio
(CMRR) of 130dB (typ).
The input common mode voltage ranges from the negative
supply up to typically 0.5V below the positive supply. The
open-loop gain is typically 140dB. The LTC2054/LTC2055
also feature a 1.6μVP-P DC to 10Hz noise and a 500kHz
gain-bandwidth product.
