Data Sheet
Application Information
General Description
The CLCx011 family of amplifiers are single supply, general
purpose, voltage-feedback amplifiers. They are fabricated
on a complimentary bipolar process, feature a rail-to-rail
input and output, and are unity gain stable.
Basic Operation
Figures 1, 2, and 3 illustrate typical circuit configurations for
non-inverting, inverting, and unity gain topologies for dual
supply applications. They show the recommended bypass
capacitor values and overall closed loop gain equations.
Figure 4 shows the typical non-inverting gain circuit for
single supply applicaitons.

Power Dissipation
Power dissipation should not be a factor when operating
under the stated 10k ohm load condition. However,
applications with low impedance, DC coupled
should be analyzed to ensure that maximum allowed
junction temperature is not exceeded. Guidelines listed
below can be used to verify that the particular application
will not cause the device to operate beyond it’s intended
operating range.
Maximum power levels are set by the absolute maximum
junction rating of 150°C. To calculate the junction
temperature, the package thermal resistance value
