Active Filters:ICs used to allow or block specific frequency ranges in a signal.
Analog-to-Digital (ADC) & Digital-to-Analog (DAC) Converters:The bridges between the "real world" (analog) and computers (digital).
Analog Switches & Multiplexers:Components that route different signals to a single output.
Temperature Sensors:Famous for theLM35series, which are still widely used by hobbyists today.
Voltage References:Precision components like theLM336orLM385that provide a steady "yardstick" voltage for other circuits.
Surface Mount:A section dedicated to the then-emerging technology of soldering components directly to the surface of a board rather than through holes.
