[Ideas For Design]
Optically isloated and powered 1-kHz ADC
Some data-conversion applications require complete galvanic isolation of the signal source from system ground. Examples include industrial process monitoring using ion-selective and pH electrodes, and biological and medical diagnostics such as... — W. Stephen Woodward

[Ideas For Design]
Serial-control multiplexer expands SPI chip selects
SPI and Microwire buses offer a popular and convenient means for minimizing the number of interconnect wires required in connecting smart peripherals to a microcontroller. These standard synchronous buses comprise a serial-clock, data-in, and data-out... — Contributing Author

[Ideas For Design]
Control circuit keeps dc motor running at constant speed
The aim of the circuit presented here is to keep the permanent magnet dc motor running at a constant speed, set externally. To do this, the current through, and the voltage across, the brushes of the motor are monitored. The voltage consists of two... — Contributing Author

[Ideas For Design]
Visible-laser driver has digitally controlled power and modulation
In the circuit presented here, a 10-bit digital-to-analog converter with a three-wire serial input operates and maintains a visible-light laser diode at constant average optical output power. A separate digital input line (MOD) enables a comparator... — Contributing Author
