10 x LM324N quad op-amps, amplifier ic's (75P post uk)
10 x LM324N QUAD OP-AMPS MANUFACTURED BY ST.
These are one of the best industry standard Op-Amp chips about. They are extremely versatile, I call it the home constructors amp because of the wide abilities and ease of use of this chip. Each IC contains 4 independant amplifier circuits that run perfectly OK from a single positive supply between 3V to 32V ( that's a good range ). With these chips you can construct any of the following;
NON INVERTING DC GAIN AMPLIFIERS. DC SUMMING AMPLIFIERS. POWER AMPLIFIER ( USES POWER TRANSISTOR FOR O/P STAGE ). CAN DRIVE LEDS DIRECTLY FROM AMP O/P. ACTIVE BANDPASS FILTERS. FIXED CURRENT SOURCES. INCANDESCENT LAMP DRIVER ( NEEDS TRANSISTOR ON O/P FOR HIGH CURRENT DRAW. CURRENT MONITORING. SQUAREWAVE OSCILLATOR AND ALSO PULSE GENERATION. VCO ( VOLTAGE CONTROLLED OSCILLATOR ).
The list goes on and is only limited by the imagination of the constructor. There is a wealth of information on the web about this IC and numerous practical circuits to build.
GOOD VALUE 10 x LM324N QUAD OP-AMPS FOR ONLY £1.99
FANTASTIC BARGAIN 10 x LM324N OP-AMPS FOR £1.99.
