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 400
Ω
 resistor), 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: 10

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 2k
Ω
 load and 12 million driving a 600
Ω
load to 
±
10V.
In the design, processing and testing of the device, particular
attention has been paid to the optimization of the entire
distribution of several key parameters. Consequently, the
specifications of even the lowest cost grades (the LT1007C
and the LT1037C) have been spectacularly improved com-
pared to equivalent grades of competing amplifiers.
The sine wave generator application shown below utilizes the
low noise and low distortion characteristics of the LT1037.
