Description
The FT1007/FT1037 series features the lowest noise
performance available to date for monolithic operational
amplifiers: 2.5nV/√Hz wideband noise (less than the noise of
a 400Ω 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: 10µV offset
voltage, 0.2µV/°C drift, 130dB common mode and power
supply rejection, and 60MHz gain bandwidth product on the
decompensated FT1037, which is stable for closed-loop
gains of 5 or greater.
The voltage gain of the FT1007/FT1037 is an extremely high
20 million driving a 2kΩ load and 12 million driving a 600Ω
load to
±10V.
In the design, processing and testing of the device, particular
attention has been paid to the optimisation of the entire
distribution of several key parameters. Consequently, the
specifications of even the lowest cost grades (the FT1007C
and the FT1037C) have been spectacularly improved com-
pared to equivalent grades of competing amplifiers.
The sine wave generator application shown below utilises the
low noise and low distortion characteristics of the FT1037.
