LTC2054/LTC2055 Single/Dual Micropower Zero-Drift Operational Amplifiers DESCRIPTIO The LTC®2054/LTC2055 are low power, low noise single/ dual zero-drift operational amplifiers available in the SOT-23 (Thin SOTTM) 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. The LTC2054/LTC2055, despite their miniature size, feature unpromising DC performance. The typical input offset voltage and offset drift are 0.5µV and 25n V/°C. The almost zero DC offset and drift are supported with a power supply rejection ratio (PSRR) and mon mode rejection ratio (CMRR) of more than 130d B. The input mon mode voltage ranges from the negative supply up to typically 0.5V from the positive supply. The open-loop gain is typically 140d B. The LTC2054/LTC2055 also feature a 1.6µVP-P DC to 10Hz noise and a 500k Hz gain-bandwidth product. , LTC and LT are registered trademarks of Linear Technology Corporation.
