(50) WP 901-76L6 LOW VOLTAGE, LOW POWER, DUAL OPAMP DIPs => LM 358 / NE 532 Equivalent, NOS ICs Linear ICs, NOS DIP ICs. This proprietary-marked IC is equivalent to the very popular, versatile and useful LM358, NE532, LM2904 and NTE928 (see Signetics "Linear Data Manual Industrial," Vol. 2) in both specs and pin-out, which I have personally verified through my own electronics lab testing. Low power supply (PS) voltage, low standby power. Because this analog IC is apparently marked with a proprietary number, it very much prevents reverse-engineering attempts on your designs, and certainly beats tedious, risky and/or insecure painting over or grinding off IC part numbers. Next to the LM555, I use this very versatile IC-type the most. Why? While most op amps get a little crazy below about 6 VDC PS - forcing you to use either a bulky 4 cells or a 9-volt battery - the nifty WP901 easily operates down to 3 VDC PS (I've used them below 2.5 VDC). The WP901 does great with only two AAA batteries, or a 3.0V watch battery! Not only that, but the WP901 will operate from single and dual power supplies. Gain and bandwidth are very good: Gain upto 100 db, and unity BW at 1 MHz, which results in good quality output in the treble and lower ultrasonic (including sonar) bands! And low offset and low bias! You can hardly ask for better! I've used them from about 0.1 Hz, through the entire audio band, and deep into the ultrasonic band (sonar band). And I find them especially useful if you must combine an op amp section with TTL, memory or data conversion logic (e.g. A/D, D/A) - requiring only one 5 VDC PS for all circuit functions. One WP901 amp section can be used for input amplification/gain control, and the other section for output amp/gain (particularly useful in digitizing audio and transducer signals applications), or cascaded with each other. If you need more power, you easily add on a transistor to the output. You can build a practical WP901 circuit about the size of a stack of 4 quarters! Versatile and easy-to-use - great for all kinds of circuit jobs you have, including class projects and science fair projects, and learning tool for electronics. Image is 10X.
