The operational amplifier is arguably the most useful single device in analog electronic circuitry. When you apply them in the circuits, you must know their basics and functions. As for the function ...

My hands-on introduction to operational amplifiers was in 1969 while in the army as a junior scientist in the Atmospheric Science Laboratory at the White Sands Proving Grounds. We had taken a ...

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 ...

Modern operational amplifiers (op amps) and instrumentation amplifiers (in amps) provide great benefits to the designer, when compared with discrete semiconductors. But all too often, some very basic ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...

The term instrumentation amplifier (INA) often is misused, referring to the application rather than the architecture of the device. Historically, any amplifier that was considered precision (i.e., ...

Guest columnist Harry Holt, applications engineer at Analog Devices, believes that two into one is a relevant question when designs need more than one operational amplifier. In designs requiring ...

In the last Circuit VR we looked at some basic op amp circuits in a simulator, including the non-inverting amplifier. Sometimes you want an amplifier that inverts the signal. That is a 5V input ...

KYOTO, Japan, Sept. 9, 2025 /PRNewswire/ -- ROHM Co., Ltd. has announced that its ultra-compact CMOS Operational Amplifier (op amp) TLR1901GXZ achieves the industry's lowest operating circuit current ...

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 ...
