This document was developed under the Standard Hardware and Reliability Program (SHARP) TechnologyIndependent Representation of Electronic Products (TIREP) project. It is intended for use by VHSIC HardwareDescription Language (VHDL) design engineers and is offered as guidance for the development of VHDL modelswhich are compliant with the VHDL DATa Item Description (DID DI-EGDS-80811) and which can be providedto manufacturing engineering personnel for the development of production DATa and the subsequent productionof hardware. Most VHDL modeling performed to date has been concentrated at either the component level orat the conceptual system level. The assembly and sub-assembly levels have been largely disregarded. Under theSHARP TIREP project, an attempt has been made to help close this gap. The TIREP models are based upon lowcomplexity Standard Electronic Modules (SEM) of the format A configuration. Although these modules are quitesimple, it is felt that the lessons learned offer guidance which can readily be applied to a wide range of assemblytypes and complexities.

The trend in ADCs and DACs is toward higher speeds and higher resolutions atreduced power levels. Modern DATa converters generally operate on ±5V (dualsupply) or +5V (single supply). In fact, many new converters operate on a single +3Vsupply. This trend has created a number of design and applications problems whichwere much less important in earlier DATa converters, where ±15V supplies and ±10Vinput ranges were the standard.

Abstract: Most magnetic read head DATa sheets do not fully specify the frequency-dependent components andare often vague when specifying other key parameters. In some cases, the specifications of two very similarheads from two different manufacturers might be quite different in terms of parameters specified and omitted.The limitations in the DATa sheets make designing an optimum card reading system unnecessarily difficult andtime consuming. This document outlines a strategy to overcome the above shortcomings and offers guidelinesto overcome the noise issues.

A MEMS microphone IC is unique among Analog Devices, Inc., products in that its input is an acoustic pressure wave. For this reason, some specifications included in the DATa sheets for these parts may not be familiar, or familiar specifications may be applied in unfamiliar ways. This application note explains the specifica-tions and terms found in MEMS microphone DATa sheets so that the microphone can be appropriately designed into a system.

Abstract: IC switches and multiplexers are proliferating, thanks to near-continual progress in lowering the supply voltage,incorporating fault-protected inputs, clamping the output voltage, and reducing the switch resistances. The latest of these advancesis the inclusion of precision resistors to allow two-point calibration of gain and offset in precision DATa-acquisition systems.

Abstract: Using a DAC and a microprocessor supervisor, the system safety can be improved in industrial controllers, programmablelogiccontrollers (PLC), and DATa-acquisition systems. The analog output is set to zero-scale (or pin-programmable midscale) when amicroprocessor failure, optocoupler failure, or undervoltage condition occurs. A simple application is shown on how to implement thisfunction.
