Nanopower Analog ICs Enable Sub-1V, Micropower Current Sensing Techniques

Current-sense amplifiers can monitor battery or solar cell currents, and are useful to estimate power capacity and remaining life. However, if the battery or solar source is a single cell, it's difficult to find a low voltage solution that works below 1V and draws just microamps. A new class of nanopower analog ICs, namely Touchstone Semiconductor's TS1001 0.8V/0.6µA op amp, makes a sub-1V supply current sense amplifier possible. With its extremely low power, the circuit can simply remain "always on", providing a continuously monitored, averaged indication of current which can be read by a microcontroller without too much current drain.

This month, Oscium is giving away three of its iMSO-204L dual analogue iOS oscilloscopes, worth USD400 each. Designed with native Lightning compatibility, the iMSO-204L transforms the iPad, iPhone, and iPod touch into an ultra-portable, two-channel oscilloscope.
Since Apple changed its connector, Oscium has been working to bring native compatibility to its customers. The third generation of handheld engineering tools from Oscium, the iMSO-204L is the solution to the connector change, featuring two analogue and four digital channels, capable of 50 MSPS at a 5MHz bandwidth, and with a resolution varying from 200ns/div to 10s/div.MORE INFO AND LAST MONTH' WINNERS...
