The LT1079 is a micropower quad op amp offered in the standard 14-pin packages. Both devices are optimized for single supply operation at 5V. ±15V specifications are also provided. Micropower performance of competing devices is achieved at the expense of seriously degrading precision, noise, speed and output drive specifications. The design effort of the LT1078/LT1079 was concentrated on reducing sup- ply current without sacrificing other parameters. The offset voltage achieved is the lowest on any dual or quad nonchopper stabilized op amp—micropower or other- wise. Offset current, voltage and current noise, slew rate and gain bandwidth product are all two to ten times better than on previous micropower op amps. The 1/f corner of the voltage noise spectrum is at 0.7Hz, at least three times lower than on any monolithic op amp. This results in low frequency (0.1Hz to 10Hz) noise performance which can only be found on devices with an order of magnitude higher supply current. Both the LT1078 and LT1079 can be operated from a single supply (as low as one lithium cell or two Ni-Cad 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. s Battery or Solar-Powered Systems Portable Instrumentation Remote Sensor Amplifier Satellite Circuitry s Micropower Sample-and-Hold s Thermocouple Amplifier s Micropower Filters Distribution of Input Offset Voltage (LT1078 and LT1079 in H, J, N Packages) INPUT OFFSET VOLTAGE ( µV) –120 0 80 1078/79 • TA02 –80 –40 40 16 14 12 10 8 6 4 2 0 120 VS = 5V, 0V TA = 25°C Single Battery, Micropower, Gain = 100, Instrumentation Amplifier INVERTING INPUT 1M 2 3 1 6 5 7 A 1/2 LT1078 10.1k 1M 10.1k NONINVERTING INPUT B 1/2 LT1078 4 8 3V (LITHIUM CELL) OUT TYPICAL PERFORMANCE INPUT OFFSET VOLTAGE = 40 µV INPUT OFFSET CURRENT = 0.2nA TOTAL POWER DISSIPATION = 240 µW COMMON MODE REJECTION = 110dB (AMPLIFIER LIMITED) GAIN BANDWIDTH PRODUCT = 200kHz OUTPUT NOISE = 85 µVP-P 0.1Hz TO 10Hz = 300 µVRMS OVER FULL BANDWIDTH INPUT RANGE = 0.03V TO 1.8V OUTPUT RANGE = 0.03V TO 2.3V (0.3mV ≤ VIN+ – VIN– ≤ 23mV) OUTPUTS SINK CURRENT—NO PULL-DOWN RESISTORS ARE NEEDED LT1078/79 • TA01 – + , LTC and LT are registered trademarks of Linear Technology Corporation.
