DESCRIPTION
gain ,internally frequency compensated operational
amplifiers which were designed specifically to
operate from a single power supply over a wide
range of voltages.Operation from split power
supplies is also possible and the low power supply
current drain is independent of the magnitude of
the power supply voltage.
DC agin blocks and all the conventional op amp
Circuits which now can be more easily.
Implemented in single power supply systems.For
Example,the IT358 can be directly operated off of
the standard -5Vpower supply voltage which is used
in digital systems and will easily provide the required
interface el

... APPLICATION HINTS The IT358 is op amps which operate with only a single power supply voltage, have true-differential inputs, and remain in the linear mode with an input common-mode voltage of 0V. These amplifiers operate over a wide range of power supply voltage with little change in performance characteristics. At 25°C a mplifier operation is possible down to a minimu m supply voltage of 2 ...
