In order to help his friend prepare for a talk at DEFCON this weekend, [Craig] built an IR photodiode amplifier circuit. The circuit extended the detection range of the hack from a few inches to a few ...

Sponsored by Texas Instruments: Operational amplifiers serve many applications, from measuring current through a shunt to converting a photoconductive photodiode’s output to a voltage. The precision ...

In some JFET op amps such as the AD743, the input capacitance is in the order of 18 to 20 pF. In comparison, with an LSK489 dual FET, the input capacitance is in the order of 3 pF, which will be ...

This new light-to-voltage converter integrates a photodiode, op amp and feedback components on a single monolithic IC. The TSL257 chip reportedly can measure very low levels of light with ...

A while back, [Chris Lu] was studying how analog circuits, specifically op-amps can be used to perform mathematical operations and wondered if they could be persuaded to solve differential equations, ...

Optimized for use as a sensing amplifier, ideally suited for space-constrained applications. Santa Clara, CA and Kyoto, Japan, Sept. 09, 2025 (GLOBE NEWSWIRE) -- ROHM Semiconductor today announced the ...
