LTC2054/LTC2055 Single/Dual Micropower Zero-Drift Operational Amplifiers FEATURES DESCRIPTION n Supply Current 150μA (Max per Amplifier) Guaranteed from –40°C to 85°C n Offset Voltage 3μV (Max, –40°C to 85°C) n Offset Voltage Drift 30nV/°C (Max, –40°C to 85°C) n Guaranteed Specifications from –55°C to 150°C (LTC2054MP) n Common Mode Input Range from V– to V+ – 0.5V n Output Swings Rail-to-Rail n Voltage Gain: 140dB (Typ) n PSRR and CMRR: 130dB (Typ) n Input Bias Current: 1pA (Typ, 25°C) n Noise: 1.6μVP-P (0.01Hz to 10Hz Typ) n Supply Operation: 2.7V to 6V (LTC2054/LTC2055) 2.7V to ±5.5V (LTC2054HV/LTC2055HV) n Low Profile (1mm) TSOT-23, MS8 and 3mm × 3mm × 0.8mm DFN Packages APPLICATIONS The LTC®2054/LTC2055 are low power, low noise, single/ dual, zero-drift operational amplifiers with an extended temperature version (LTC2054MP) that has guaranteed specifications from –55°C to 150°C. They are available in TSOT-23 (ThinSOT™) 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 uncompromising DC performance. The maximum input offset voltage and offset drift are 3.0μV and 30nV/°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 common mode rejection ratio (CMRR) of 130dB (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 common mode voltage ranges from the negative supply up to typically 0.5V below the positive supply. The open-loop gain is typically 140dB. The LTC2054/LTC2055 also feature a 1.6μVP-P DC to 10Hz noise and a 500kHz gain-bandwidth product.
