FEATURES

LTC2054/LTC2055

Single/Dual Micropower

Zero-Drift Operational Ampliﬁers

DESCRIPTION

The LTC

2054/LTC2055 are low power, low noise, single/

dual, zero-drift operational ampliﬁers with an extended

temperature version (LTC2054MP) that has guaranteed

speciﬁcations 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

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, 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 1.6μV

P-P

DC to 10Hz noise and a 500kHz

gain-bandwidth product.
