What a bridge puts out, and how small it is A bridge is specified in millivolts per volt of excitation. TI’s guide puts load cells at 1 to 3 mV/V and works an example at 2 mV/V: 5 V of excitation gives 10 mV at full scale. Each output sits at half the excitation, so […]

Recently I needed to actually “see” a current waveform in the 100 uA to 5 mA range with at least a couple MHz bandwidth. This extremely expensive probe would have been perfect, but instead I built something similar for about $30 using the amazing Analog Devices AD8428 amplifier. Click “Read more” for details and a

This is a low frequency amplifier with an adjustable transimpedance that is intended to be used to take relative measurements of a wide range of photo currents. Not having many parts, this amplifier can be put together in a short amount of time. Find updates at www.projects.cappels.org Introduction I needed to make some relative optical
