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 specifi cations 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 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.
