LTC2050/LTC2050HV Zero-Drift Operational Amplifiers in SOT-23 FEATURES DESCRIPTION n Maximum Offset Voltage of 3V The LTC 2050 and LTC2050HV are zero-drift operational n Maximum Offset Voltage Drift of 30nV/C amplifiers available in the 5- or 6-lead SOT-23 and SO-8 n Noise: 1.5V (0.01Hz to 10Hz Typ) packages. The LTC2050 operates from a single 2.7V to P-P n Voltage Gain: 140dB (Typ) 6V supply. The LTC2050HV operates on supplies from n PSRR: 130dB (Typ) 2.7V to 5.5V. The current consumption is 800A and n CMRR: 130dB (Typ) the versions in the 6-lead SOT-23 and SO-8 packages n Supply Current: 0.8mA (Typ) offer power shutdown (active low). The LTC2050HVMP n Supply Operation offer operating range from 4.5V to 5.5V and operating n LTC2050: 2.7V to 6V temperature range of 55C to 150C. n LTC2050HV: 2.7V to 5.5V The LTC2050, despite its miniature size, features uncom- n LTC2050HVMP: 4.5V to 5.5V promising DC performance. The typical input offset volt- n Extended Common Mode Input Range age and offset drift are 0.5V and 10nV/C. The almost n Output Swings Rail-to-Rail zero DC offset and drift are supported with a power sup- n Input Overload Recovery Time: 2ms (Typ) ply rejection ratio (PSRR) and common mode rejection n Operating Temperature Range ratio(CMRR) of more than 130dB. n LTC2050: 40C to 125C n The input common mode voltage ranges from the nega- LTC2050HVMP: 55C to 150C n tive supply up to typically 1V from the positive supply. Low Profile (1mm) SOT-23 (ThinSOT) Package n The LTC2050 also has an enhanced output stage capable AEC-Q100 Qualified for Automotive Applications of driving loads as low as 2k to both supply rails. The open-loop gain is typically 140dB. The LTC2050 also APPLICATIONS features a 1.5V DC to 10Hz noise and a 3MHz gain P-P n Thermocouple Amplifiers bandwidth product. n Electronic Scales All registered trademarks and trademarks are the property of their respective owners.
