LT1007IS8

高速运算放大器 LT1007 - Low Noise, High Speed Precision Operational Amplifiers

DESCRIPTION

The LT®1007/LT1037 series features the lowest noise performance available to date for monolithic operational amplifiers: 2.5nV/√Hz wideband noise less than the noise of a 400Ωresistor, 1/f corner frequency of 2Hz and 60nV peak to-peak 0.1Hz to 10Hz noise. Low noise is combined with

outstanding precision and speed specifications: 10µV offset voltage, 0.2µV/°C drift, 130dB common mode and power supply rejection, and 60MHz gain bandwidth product on the

decompensated LT1037, which is stable for closed-loop gains of 5 or greater.

The voltage gain of the LT1007/LT1037 is an extremely high 20 million driving a 2kΩload and 12 million driving a 600Ω load to ±10V.
