LT1881/LT1882 Dual and Quad Rail-to-Rail Output, Picoamp Input Precision Op Amps FEATURES DESCRIPTION n Offset Voltage: 50V Maximum (LT1881A) The LT 1881 and LT1882 op amps bring high accuracy n Input Bias Current: 200pA Maximum (LT1881A) input performance to ampli ers with rail-to-rail output n Offset Voltage Drift: 0.8V/C Maximum swing. Input bias currents and capacitive load driving n Rail-to-Rail Output Swing capabilities are superior to the similar LT1884 and LT1885 n Supply Range: 2.7V to 36V ampli ers, at the cost of a slight loss in speed. Input n Operates with Single or Split Supplies offset voltage is trimmed to less than 50V and the n Open-Loop Voltage Gain: 1 Million Minimum low drift maintains this accuracy over the operating n 1mA Maximum Supply Current Per Ampli er temperature range. Input bias currents are an ultralow n Stable at A = 1, C = 1000pF 200pA maximum. V L n Standard Pinouts The ampli ers work on any total power supply voltage n Wide Operating Temperature Range: between 2.7V and 36V (fully speci ed from 5V to 15V). 55C to 125C (LT1882) Output voltage swings to within 40mV of the negative supply and 220mV of the positive supply make these ampli ers good choices for low voltage single supply APPLICATIONS operation. n Thermocouple Ampli ers n Capacitive loads up to 1000pF can be driven directly in Bridge Transducer Conditioners n unity-gain follower applications. Instrumentation Ampli ers n Battery-Powered Systems The dual LT1881 and LT1881A are available with standard n Photo Current Ampli ers pinouts in S8 and PDIP packages.
