(50) LM 358N LOW VOLTAGE, LOW POWER,
DUAL OP AMP DIPs => NE 532, DIP, NOS ICs
NOS DIP ICs. The famous LM358 Dual Amp IC is equiv. to the NE532, LM2904 and NTE928 (see Signetics "Linear Data Manual Industrial," Vol. 2) in both specs and pin-out. Low power supply (PS) voltage, low standby power.
Next to the LM555, I use this very versatile IC 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 LM358 easily operates down to 3 VDC PS (I've used them below 2.5 VDC). The LM 358 does great with only two AAA batteries, or a watch battery! Not only that, but the LM358 will operate from single or dual power supplies. Gain and bandwidth are very good: Gain upto 100 db, and unity BW at 1 MHz! And low offset and low bias! You can hardly ask for better! I've used them from DC and 0.01 Hz (transducer input), through the entire audio band, and deep into the ultrasonic band for sonar applications.
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 LM358 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 single transistor or push-pull pair to the output. You can build a practical LM358 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 and science fair projects, and learning tool for electronics. Image is 10X.
