With 12-in. silicon wafers now in production, achieving precision performance across tens of thousands of amplifiers requires fast and accurate tuning to keep cost low.

An interesting analog design problem is the precision current source. Many good designs are available, but most are the three-wire types that can be used as a positive (see Figure 1) or a negative ...

It’s always a pleasure to find a hardware hacker who you haven’t seen before, and page back through their work. [Bettina Neumryr]’s niche comes in building projects from old electronics magazines, and ...

According to ROHM, its ultra-compact TLR1901GXZ CMOS op amp is the industry’s lowest operating circuit current. The op amp is built to be used as a measurement-sensing amplifier in space-constrained ...

At first glance, [RobBest]’s constant current source looks old school. The box is somewhat old-fashioned, featuring switches and binding posts. Most importantly, there’s a large analog meter ...

Abstract: A current source is one of the most important circuits in Electrical Impedance Tomography (EIT) hardware systems for measuring conductive multiphase flows. One of its important and ...

The ADHV4710 op amp operates on dual supplies from ±12 to ±55 V, delivering output current of ±100 mA at the higher voltages. A ±1,300-V/μs output slew rate into capacitive loads up to 1 nF (1000 pF).

Operational amplifiers (op amps) may initially look intimidating, but with a bit of study, they can be easily understood and used in a variety of applications. Op amps can be thought of as a perfect ...

The LM4041 has been around for over 20 years. During those decades, while primarily marketed as a precision adjustable shunt regulator, this classic device also found its way into alternative ...
