LT1413 Single Supply, Dual Precision Op Amp DESCRIPTIO FEATURES Single Supply Operation: The LT1413 is a low cost, upgraded version of Linear n Input Goes Below Ground Technologys industry standard LT1013 dual, single sup- n Output Swings to Ground Sinking Current ply op amp. The LT1413 is optimized for single 5V appli- n No Pull-Down Resistors Needed cations, although 15V specifications are also provided n Phase Reversal Protection for completeness. At 5V, 0V Low Cost Grade Specifications: In the design of the LT1413, particular emphasis has been n 280V Max Offset Voltage placed on low cost plastic and SO-8 package performance: n 380V Max in S8 Package 60V offset voltage, 0.1nA offset current, in excess of n 0.8nA Max Offset Current 10mA output current at 330A supply current and 140dB n 480A Max Supply Current per Amplifier channel separation are some of the specifications achieved. n 0.5V/C Drift n Other dual, single supply amplifiers are available to 1.4 Million Voltage Gain n complement the LT1413 family: the micropower LT1078s 950kHz Gain-Bandwidth Product n supply current is 10 times lower with a 4.5 fold speed 0.55V , 0.1Hz to 10Hz Noise P-P performance degradation compared to the LT1413. Con- versely, the LT1211, LT1213 and LT1215 duals have 4 to APPLICATI S 14 times higher supply current, but also 13 to 50 times higher speed. n Single Supply Systems Protected by U.S. Patent 4,775,884. n Two and Three Op Amp Instrumentation Amplifiers n Active Filters n Battery-Powered Systems n Strain Gauge and Bridge Amplifiers TYPICAL APPLICATI Distribution of Input Offset Voltage +90V, 3V Common-Mode Range (In Plastic DIP, N8 Package) Difference Amplifier (A = 1) V 30 10M V = 5V, 0V S T = 25C A 25 9V 10M 2 8 20 1 OUTPUT INPUT 1/2 LT1413 20mV TO 8V 10M 1M 15 3 + + 4 1M 10 5 10M OUTPUT OFFSET = 1.5mV (THE 0.1nA TYPICAL OFFSET CURRENT 0 (INPUT REFERRED = 125V) PERMITS THE USE OF 1M RESISTORS) 300 200 100 0 100 200 300 INPUT RESISTANCE = 11M INPUT OFFSET VOLTAGE (V) BANDWIDTH = 80kHz LT1413 TA03 LT1413 TA01 1 PERCENT OF UNITS UO UO ULT1413 O ABS LUTEXAI U RATI GS Supply Voltage ..................................................... 22V Output Short-Circuit Duration .........................
