The operating frequency about ic components LTC1736

Do you know The operating frequency about electronic components,such as electronic component LTC1736?
May be you only know characteristics or description.

The operating frequency (synchronizable up to 500kHz) about ic components LTC1736 is  set by an external capacitor allowing maximum flexibility in optimizing efficiency. The  output voltage is monitored by a power good window comparator that indicates when the  output is within 7.5% of its programmed value.

Protection features include: internal foldback current limiting,output overvoltage  crowbar and optional short-circuit shutdown. Soft-start is provided by an external  capacitor that can be used to properly sequence supplies.

The General Description about ic components LM101A/LM201A/LM301A

The electronic components LM101A series are general purpose operational amplifiers
which feature improved performance over industry standards
like the electronic component LM709 and ic components LM101A. Advanced processing techniques make possible an order of magnitude reduction in input currents,
and a redesign of the biasing circuitry reduces the
temperature drift of input current. Improved specifications include:
• Offset voltage 3 mV maximum over temperature
(LM101A/LM201A)
• Input current 100 nA maximum over temperature
(LM101A/LM201A)
• Offset current 20 nA maximum over temperature
(LM101A/LM201A)
• Guaranteed drift characteristics
• Offsets guaranteed over entire common mode and supply
voltage ranges
• Slew rate of 10V/μs as a summing amplifier

Description of ic components LM358W and LM358AW

Description about electronic component LM358W and LM358AW three follows:
one:These circuits consist of two independent, highgain,internally frequency- compensated which were designed specifically to operate from a single power supply over  a wide range of voltages.

Two:The low power supply drain is independent of the magnitude of the power supply  voltage.Application areas include transducer amplifiers, DC gain blocks and all the  conventional op-amp circuits which now can be more easily implemented in single power  supply systems. For example, these circuits can be directly supplied with the standard  +5V which is used in logic systems and will easily provide the required interface  ic components without requiring any additional power supply.

Three:In the linear mode the input common-mode voltage range includes ground and the  output nvoltage can also swing to ground, even though operated from only a single power supply voltage.
