Detailed Functional Diagram

Circuit Level Applications

• Vary the gain of a voltage amplifier

• Provide programmable dc reference voltages for

comparators and detectors

• Control the volume in audio circuits

• Trim out the offset voltage error in a voltage amplifier

circuit

• Set the output voltage of a voltage regulator

• Trim the resistance in Wheatstone bridge circuits

• Control the gain, characteristic frequency and

Q-factor in filter circuits

• Set the scale factor and zero point in sensor signal

conditioning circuits

• Vary the frequency and duty cycle of timer ICs

• Vary the dc biasing of a pin diode attenuator in RF circuits

• Provide a control variable (I, V, or R) in feedback circuits

System Level Applications

• Adjust the contrast in LCD displays

• Control the power level of LED transmitters in

communication systems

• Set and regulate the DC biasing point in an RF power

amplifier in wireless systems

• Control the gain in audio and home entertainment systems

• Provide the variable DC bias for tuners in RF wireless

systems

• Set the operating points in temperature control systems

• Control the operating point for sensors in industrial

systems

• Trim offset and gain errors in artificial intelligent systems

NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin

plate termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are

MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
