LT1880 SOT-23, Rail-to-Rail Output, Picoamp Input Current Precision Op Amp FEATURES DESCRIPTION n Offset Voltage: 150V Max The LT 1880 op amp brings high accuracy input perfor- n Input Bias Current: 900pA Max mance and rail-to-rail output swing to the SOT-23 package. n Offset Voltage Drift: 1.2V/C Max Input offset voltage is trimmed to less than 150V and n Rail-to-Rail Output Swing the low drift maintains this accuracy over the operating n Operates with Single or Split Supplies temperature range. Input bias current is an ultralow 900pA n Open-Loop Voltage Gain: 1 Million Min maximum. n 1.2mA Supply Current The ampli er works on any total power supply voltage n Slew Rate: 0.4V/s between 2.7V and 36V (fully speci ed from 5V to 15V). n Gain Bandwidth: 1.1MHz Output voltage swings to within 55mV of the negative n Low Noise: 13nV/Hz at 1kHz supply and 250mV of the positive supply, which makes n Low Pro le (1mm) ThinSOT Package the ampli er a good choice for low voltage single supply operation. APPLICATIONS Slew rates of 0.4V/s with a supply current of 1.2mA give n Thermocouple Ampli ers superior response and settling time performance in a low n Bridge Transducer Conditioners power precision ampli er. n Instrumentation Ampli ers n Battery-Powered Systems The LT1880 is available in a 5-lead SOT-23 package. n Photocurrent Ampli ers L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
