Data Acquisition System uses Fault Protection:  04/15/04 EDN Design Ideas  /  (added 02/05)  Sensitive systems, such as those in aircraft, must withstand fault conditions, thereby avoiding component and system damage, because a sensor failure could cause a catastrophic event to occur. A channel protector, comprising two n-channel MOSFETs connected in series with a p-channel MOSFET, can protect sensitive components from voltage transients in the signal path, whether or not the power sup......

Digital-Output Sensor Simplifies Temperature Acquisition:  The TMP03* is a complete temperature data-acquisition system on a monolithic silicon chip. Including a silicon-based sensor, internal voltage reference, and sigma-delta A/D converter, it fits in a 3-pin (power, common, and output) TO-92 transistor package. Its digital output is a low-frequency variable-duty-cycle serial data stream, available at an open collector with 5-mA sink-current available. A companion product, the TMP04, is identical but has a CMOS/TTL-compatible output. The quiescent power requirement is a modest 1.3 mA at +5 V (4.5 to 7-V range)... (app note added 6/06)
