It operates from a single 2.7V supply while still supporting ±5V applica- tions. The power consumption is 750 µA per op amp. The LTC2051, despite its miniature size, features uncom- promising DC performance. The typical input offset volt- age and offset drift are 0.5 µV and 10nV/°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 1V from the positive supply. The LTC2051 also has an enhanced output stage capable of driving loads as low as 1k Ω to both supply rails. The open-loop gain, loaded with 1k Ω,isinexcessof140dB.TheLTC2051 also features a 1.5 µVP-P DCto10Hznoiseanda3MHzgain bandwidth product.
