They are available in TSOT-23 (Thin SOT™) 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 maximum input offset voltage and offset drift are 3.0μV and 30n V/°C over the - 40°C to 85°C industrial temperature range. The almost zero DC offset and drift are supported with a power supply rejection ratio (PSRR) and mon mode rejection ratio (CMRR) of 130d B (typ). n Thermocouple Amplifiers n Electronic Scales n Medical Instrumentation n Strain Gauge Amplifiers n High Resolution Data Acquisition n DC Accurate RC Active Filters n Low Side Current Sense n Battery-Powered Systems The input mon mode voltage ranges from the negative supply up to typically 0.5V below the positive supply. The open-loop gain is typically 140d B. The LTC2054/LTC2055...
