February 28, 2008[Design View / Design Solution] Zero-Drift IA Takes The Strain Out Of Sensor Measurements
Sensor measurements typically translate physical phenomena of interest into electronic-circuit parameters such as resistance and capacitance, which can then be read with a bridge circuit. Bridge circuits produce an output voltage or current signal that is ratiometric with respect to temperature and powersupply voltages, thereby enabling the measurement system to be immune to these variables. Sensor examples can include: Thermistors for temperature...
October 25, 2007[Ideas For Design] Protect Current-Sense Amplifiers Against Overvoltage Transients
Certain current-sense amplifiers have to contend with frequent overvoltages. For example, a current-sense amplifier that monitors batterydischarge currents in an automobile must withstand high-voltage "load dump" pulses produced when loads are disconnected from the battery. This causes inductive spikes and overvoltages at the output of the alternator. If these pulses exceed the amplifier's common-mode voltage, the amplifier requires external...
