Use a Comparator or Op-Amp to Simplify Light Dependent Resistor Output
If your project calls for light sensitivity, it’s hard to beat light dependent resistors (LDRs), also known as photoresistors. They’re available for a few cents each, and their resistance varies based on how much light they receive. In the dark, these devices produce resistances in...

Op amps, comparators – smaller than ever
Aimee Kalnoskas @ eeworldonline.com discuss about TI's tiny OPAMP and comparators. Texas Instruments introduced the industry’s smallest operational amplifier and low-power comparators at 0.64 mm2. As the first amplifiers in the compact X2SON package, the TLV9061 op amp and TLV7011...

Simple nanosecond-width pulse generator provides high performance
by Jim Williams @ edn.com If you need to produce extremely fast pulses in response to an input and trigger, such as for sampling applications, the predictably programmable short-time-interval generator has broad uses. The circuit of Figure 1, built around a quad high-speed comparator...

Introduction to OPAMPs and Applications
Operational amplifiers (OPAMPs) are high performance differential amplifiers in integrated form that can be used in many different ways. A typical OPAMP has a non-inverting input, an inverting input, two dc power pins, one output pin and a few other fine-tuning pins. On the following...
