LTC2054 - 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 (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 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 f 528 rom 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.
