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 applications.

Power dissipation should not be a factor when operating
under the stated 10kΩ load condition. However, applications
with low impedance, DC coupled loads 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 Theta
JA
(
