1 / 12 page LT1178/LT1179 1 11789fb The LT ®1178 is a micropower dual op amp in the standard 8-pin configuration; the LT1179 is a micropower quad op amp offered in the standard 14-pin packages. Both devices are optimized for single supply operation at 5V. Specifications are also provided at ±15V supplies. The extremely low supply current is combined with true precision specifications: offset voltage is 30µV, offset current is 50pA. Both offset parameters have low drift with temperature. The 1.5pAp-p current noise and picoampere offset current permit the use of megaohm level source resistors without introducing serious errors. Voltage noise, at 0.9µVp-p, is remarkably low considering the low supply current. Both the LT1178 and LT1179 can be operated from a single supply (as low as one lithium cell or two NiCd batteries). The input range goes below ground. The all-NPN output stage swings to within a few millivolts of ground while sinking current—no power consuming pull down resistors are needed. For applications where three times higher supply current is acceptable, the micropower LT1077 single, LT1078 dual and LT1079 quad are recommended. The LT1077/78/79 have significantly higher bandwidth, slew rate, lower voltage noise and better output drive capability. ■ 17µA Max Supply Current per Amplifier ■ 70µV Max Offset Voltage ■ 250pA Max Offset Current ■ 5nA Max Input Bias Current ■ 0.9µVP-P 0.1Hz to 10Hz Voltage Noise ■ 1.5pAP-P 0.1Hz to 10Hz Current Noise ■ 0.5µV/°C Offset Voltage Drift ■ 85kHz Gain-Bandwidth Product ■ 0.04V/µs Slew Rate ■ Single Supply Operation: Input Voltage Range Includes Ground Output Swings to Ground While Sinking Current No Pull Down Resistors are Needed ■ Output Sources and Sinks 5mA Load Current 17µA Max, Dual and Quad, Single Supply, Precision Op Amps Self-Buffered, Dual Output, Micropower Reference Supply Current vs Temperature ■ Battery or Solar Powered Systems Portable Instrumentation Remote Sensor Amplifier Satellite Circuitry ■ Micropower Sample-and-Hold ■ Thermocouple Amplifier ■ Micropower Filters TEMPERATURE (°C) –50 10 12 14 16 –25 0 25 50 LT1178/LT1179 • TA02 75 18 20 100 VS = ±15V VS = 5V, 0V VS = ±1.5V FEATURES DESCRIPTIO APPLICATIO S TYPICAL APPLICATIO + – – + 2 2M 1M* 1M* 1 250k* 0.1µF 0.1µF LT1004-1.2 1/2 LT1178 1/2 LT1178 4 6 5 8 4V TO 9V 1.2365V OUTPUT 2.470V OUTPUT TOTAL BATTERY CURRENT OUTPUT ACCURACY TEMPERATURE COEFFICIENT LOAD REGULATION LINE REGULATION * = 28µA = ± 0.4% MAX = 20ppm/°C = 25ppm/mA, IL ≤ 5mA, V + ≥ 5V = 10ppm/V = 0.1% FILM RESISTORS 7 3 LT1178/LT1179 • TA01 , LTC and LT are registered trademarks of Linear Technology Corporation. |
