LTC2055HV - Single/Dual Micropower Zero-Drift Operational Amplifiers
The LTC2054 LTC2055 are low power, low noise single/ dual zero-drift Operational Amplifiers available in the SOT-23 (ThinSOT) and MS8 packages. For space limited applications, the LTC2055 is also available in a 3mm x 3mm x 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 typic 54f ally 150A for the LTC2054 and 130A/amp for the LTC2055.
The LTC2054 LTC2055 despite their miniature size, feature uncompromising DC performance. The typical input offset voltage and offset drift are 0.5V and 25nV/C. The almost zero DC offset and drift are supported with a power supply rejection ratio (PSRR) and common mode rejection ratio (CMRR) of more than 130dB.
The input common mode voltage ranges from the negative supply up to typically 0.5V from the positive supply. The open-loop gain is typically 140dB. The LTC2054 LTC2055 also feature a 1.6VP-P DC to 10Hz noise and a 500kHz gain-bandwidth product.
