The typical input Extended Common Mode Input Range offset voltage and offset drift are 0.5V and 10nV/C. The Output Swings Rail-to-Rail almost zero DC offset and drift are supported with a power Operating Temperature Range 40C to 125C supply rejection ratio (PSRR) and common mode rejec- Available in 3mm 3mm 0.8mm DFN Package tion ratio (CMRR) of more than 130dB. U APPLICATIO S The input common mode voltage ranges from the negative supply up to typically 1V from the positive supply. The Thermocouple Amplifiers LTC2051/LTC2052 also have an enhanced output stage Electronic Scales capable of driving loads as low as 2k to both supply rails. Medical Instrumentation The open-loop gain is typically 140dB. The LTC2051/ Strain Gauge Amplifiers LTC2052 also feature a 1.5V DC to 10Hz noise and a P-P High Resolution Data Acquisition 3MHz gain-bandwidth product.
