Op-Amp Microphone Preamplifier - A high quality microphone preamplifier using a single power supply, suitable for dynamic or electret microphones. The op-amp used can be any low noise, high performance type, e. g. NE5534, TL071, OPA 371 etc __ Designed by Andy Collison
Op-Amp Oscillators Simplify RF Design - 10/10/96 EDN-Design Ideas Figure 1 shows a novel circuit that uses a low-cost, high-speed op amp as a crystal-controlled RF sine-wave oscillator. An op-amp oscillator offers several advantages. Because an op amp is a complete amplifier with a high-impedance input Design by Charles Kitchin, Analog Devices, Wilmington, MA
Opamp Radio - Here is a simple radio that is easy to build and inexpensive. In fact, you probobly have all the parts you need in your junk box. You'll be suprised at the great reception with this little set. __ Designed by Aaron Cake
Op-Amp Rectifier Signals Input State - 07/21/94 EDN-Design Ideas The op-amp rectifier in Fig 1 operates from a single supply and provIdeas a logic output and an LED that indicate the state of the input voltage. The input-state indications are handy for calibration. Because the circuit operates from a single supply, the 2.5V reference determines the level around which the circuit rectifies input waveforms Design by Lee E Scaggs, High Country TEK, Nevada City, CA
