Data Logging

The LM12458 family of data acquisition system (DAS) components offers a self-calibrating, 12-bit a sign A/D converter with choice of single ended, fully differential, or mixed inputs, with on-chip differential reference, 4 or 8-input analog multiplexer, sample-and-hold, an impressive, flexible programmable logic system and a choice of speed/power combinations...

This application note shows how to interface Motorola`s MC68HC11 family of microcontrollers to the LM12458 parallel data acquisition system (DAS). It is intended to give the reader a better understanding of the DAS and how it can be integrated in a mP/mC system. There is a brief description of the MC68HC11Ax and the LM12458. An example is provided that will illustrate how to use the DAS in a system where a specific sampling rate is desired, single-ended and differential measurements of multiple channels need to be made, and alarm conditions must be monitored...

This application note provides a graphical reference to popular connector pin assignments (pin outs) that are commonly used in telecom and computing applications. In the field of data communication, the cable and connector play a critical part in the systems performance along with the line driver and receiver integrated circuits. Together the components (PCBs, ICs, cables, and connectors) form a channel, which all information must pass through. This channel forms a true chain, and a fault in any link may break the chain...

The scope of this application note is to introduce common data transmission parameters and to provide their definitions. This application note is subdivided into five sections, which are: Voltage Parameters Current Parameters Timing Parameters Miscellaneous Parameters Truth Table Explanations Each parameter definition typically includes the following information: symbol, full name, description of measurement, measurement diagram, and a list of alternate names where applicable...

The LM12454/8 family of data acquisition system (DAS) chips offers a fully differential self-calibrating 12-bita sign A/D converter with differential reference, 4 or 8 input analog multiplexer and extensive flexible and programmable logic...

The LTC®2400 is the industrys first No Latency TM ADC that combines automatic offset and full-scale calibration, an internal oscillator, a sinc4 digital filter, and serial I/O to yield a 24-bit ADC with 1.5µVRMS input noise and singleshot conversion time architecture. It is the ideal A/D converter for temperature measurement and high effective resolution instrumentation applications, such as digital multimeters...
