Though current feedback operational amplifiers (CFOAs) are still less common in educational circles and technical literature than voltage feedback operational amplifiers (VFOAs or VFAs), they have ...

Author Mazi Hosseini describes a simple, low-cost, voltage-controlled current source using two op amps that provides a good range of current and maximum load. One challenge in circuit design is ...

This Application Note will discuss the procedures used to obtain a test platform that is capable of measuring nano volts and femto amps down to 0.1Hz. The test platform’s capability is illustrated by ...

Power operational amplifiers (POPs) are becoming increasingly common in control circuitry. Their primary advantages over conventional amplifiers are reduced part counts, increased reliability, and ...

Fig 1. This modified Wien-Bridge oscillator has three output states—high, low, and oscillation—that depend on the input voltage. It drives a bi-color LED to provide a visual indication of the input’s ...

Diodes Incorporated (Nasdaq:DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete and analog semiconductor markets, ...

If you’ve ever wondered why an op amp has the little plus and minus symbols on it, its because at the heart of it, the device is a differential amplifier. The problem is that — ideally, at least — it ...

Comparison of Low-Power Op Amp Characteristics ROHM's TLR1901GXZ ranks among the best in ultra-low current op amps at approximately 45% lower than typical products on the market. Santa Clara, CA and ...

Are your jellybeans getting stale? [lcamtuf] thinks so, and his guide to choosing op-amps makes a good case for rethinking what parts you should keep in stock. For readers of a certain vintage, the ...
