The OPA140, OPA2140, and OPA4140 op amp family is a series of low-power JFET input amplifiers that feature good drift and low input bias current. The rail-to-rail output swing and input range that ...

The ADA4610-2 is a dual precision JFET amplifier that features low offset voltage, low input bias current, low input voltage noise, low input current noise, and rail-to-rail output. The ADA4610-2 is a ...

Coming on the scene as the first precision JFET amplifier in an SC70 package, the AD8627 features single-supply operation from 5V to 26V and lower input bias currents than its predecessor, the AD820.

1. This circuit uses a JFET to bootstrap the cathode of the photodiode. It eliminates the effect of diode resistance and capacitance. This improves bandwidth and reduces noise, but puts a dc voltage ...

Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

Dipping into the Linear Integrated Systems website again, revealed another interesting app note on fet amplifier front-ends, written around the firm’s LSK489 monolithic dual low-noise n-fet. Called, ...

Normally, if you want to control the gain of an amplifier, you’ll use a variable resistor. You know, like a volume control. But what if you want to control the amplifier’s gain with a voltage?
