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 ...

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 ...

In this section we shall discuss the interface between a photosensor and its associated electronics. There are really just two photocell applications – light measurement, and the reception of ...

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 ...
