DESCRIPTION
V The LTC®2054/LTC2055 are low power, low noise single/dual zero-drift operational amplifiers available in the SOT-23 (ThinSOTTM) 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.
