LT1880 SOT-23, Rail-to-Rail Output, Picoamp Input Current Precision Op Amp
FEATURES DESCRIPTION
n
Offset Voltage: 150μV 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: 1.2μV/°C Max
Input offset voltage is trimmed to less than 150μV 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 amplifi er works on any total power supply voltage n Slew Rate: 0.4V/μs between 2.7V and 36V (fully specifi 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 Profi le (1mm) ThinSOT™ Package the amplifi er a good choice for low voltage single supply operation.
APPLICATIONS
Slew rates of 0.4V/μs with a supply current of 1.2mA give n Thermocouple Amplifi ers superior response and settling time performance in a low n Bridge Transducer Conditioners power precision amplifi er. n Instrumentation Amplifi ers n Battery-Powered Systems The LT1880 is available in a 5-lead SOT-23 package. n Photocurrent Amplifi ers L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks of Linear Technology Corporation.
