LT1007/LT1037 Low Noise, High Speed Precision Operational Amplifiers FEATURES DESCRIPTIO n Guaranteed 4.5nV/ Hz 10Hz Noise The LT 1007/LT1037 series features the lowest noise n Guaranteed 3.8nV/ Hz 1kHz Noise performance available to date for monolithic operational n 0.1Hz to 10Hz Noise, 60nV Typical amplifiers: 2.5nV/ Hz wideband noise (less than the noise of P-P n Guaranteed 7 Million Min Voltage Gain, R = 2k a 400W resistor), 1/f corner frequency of 2Hz and 60nV peak- L n Guaranteed 3 Million Min Voltage Gain, R = 600W to-peak 0.1Hz to 10Hz noise. Low noise is combined with L n Guaranteed 25m V Max Offset Voltage outstanding precision and speed specifications: 10m V offset n Guaranteed 0.6m V/ C Max Drift with Temperature voltage, 0.2m V/ C drift, 130dB common mode and power n Guaranteed 11V/m s Min Slew Rate (LT1037) supply rejection, and 60MHz gain bandwidth product on the n Guaranteed 117dB Min CMRR decompensated LT1037, which is stable for closed-loop gains of 5 or greater. U APPLICATIO S The voltage gain of the LT1007/LT1037 is an extremely high 20 million driving a 2kW load and 12 million driving a 600W n Low Noise Signal Processing load to 10V. n Microvolt Accuracy Threshold Detection In the design, processing and testing of the device, particular n Strain Gauge Amplifiers attention has been paid to the optimization of the entire n Direct Coupled Audio Gain Stages distribution of several key parameters. Consequently, the n Sine Wave Generators specifications of even the lowest cost grades (the LT1007C n Tape Head Preamplifiers and the LT1037C) have been spectacularly improved com- n Microphone Preamplifiers pared to equivalent grades of competing amplifiers.
