Description
The FT1001 significantly advances the state-of-the-
art of precision operational amplifiers. In the design,
processing, and testing of the device, particular atten-
tion has been paid to the optimisation of the entire
distribution of several key parameters. Consequently,
the specifications of the lowest cost, commercial tem-
perature device, the FT1001C, have been dramatically
improved when compared to equivalent grades of com-
peting precision amplifiers.
Essentially, the input offset voltage of all units is less
than 50µV (see distribution plot below). This allows the
FT1001AMB to be specified at 15µV. Input bias and
offset currents, common-mode and power supply re-
jection of the FT1001C offer guaranteed performance
which were previously attainable only with expensive,
selected grades of other devices. Power dissipation is
nearly halved compared to the most popular precision
op amps, without adversely affecting noise or speed
performance. A beneficial by-product of lower dissipa-
tion is decreased warm-up drift. Output drive capability
of the FT1001 is also enhanced with voltage gain
guaranteed at 10mA of load current. For similar perfor-
mance in a dual precision op amp, with guaranteed
matching specifications, see the FT1002. Shown below
is a platinum resistance thermometer application.
