Abstract: This application note describes how sampling clock jitter (time interval error or "TIE jitter") affectsthe performance of delta-sigma digital-to-analog converters (DACs). New insights explain the importanceof separately specifying low-frequency (< 2x passband frequency) and high-frequency or wideband (> 2xpassband frequency) jitter tolerance in these devices. The article also provides an application example ofa simple highly jittered cycle-skipped sampling clock and describes a method for generating a properbroadband jittered clock. The document then goes on to compare Maxim's audio DAC jitter tolerance tocompetitor audio DACs. Maxim's exceptionally high jitter tolerance allows very simple and low-cost sampleclock implementations.

The MAX17600–MAX17605 devices are high-speedMOSFET drivers capable of sinking /sourcing 4A peakcurrents. The devices have various inverting and noninvertingpart options that provide greater flexibility incontrolling the MOSFET. The devices have internal logiccircuitry that prevents shoot-through during output-statchanges. The logic inputs are protected against voltagespikes up to +14V, regardless of VDD voltage. Propagationdelay time is minimized and matched between the dualchannels. The devices have very fast switching time,combined with short propagation delays (12ns typ),making them ideal for high-frequency circuits. Thedevices operate from a +4V to +14V single powersupply and typically consume 1mA of supply current.The MAX17600/MAX17601 have standard TTLinput logic levels, while the MAX17603 /MAX17604/MAX17605 have CMOS-like high-noise margin (HNM)input logic levels. The MAX17600/MAX17603 are dualinverting input drivers, the MAX17601/MAX17604 aredual noninverting input drivers, and the MAX17602 /MAX17605 devices have one noninverting and oneinverting input. These devices are provided with enablepins (ENA, ENB) for better control of driver operation.

Abstract: This application note presents an overview of the operational characteristics of accurate I²C real-time clocks (RTCs),including the DS3231, DS3231M, and DS3232. It focuses on general application guidelines that facilitate use of device resources forpower management, I²C communication circuit configurations, and I²C characteristics relative to device power-up sequences andinitializations. Additional discussions on decoupling are provided to support developing strategies for mitigating power-supply pushingof device frequency.

Digital convergence, in recent history, has been prevalentin the consumer equipment domain and the designengineers in this area have been struggling with a plethoraof emerging standards and protocols. What lessons can welearn from their struggle? The same dilemmas now existin in-vehicle telematics and infotainment systems but withthe added issues of extremes of temperature, safety,security, and time in market.

Control systems are becoming increasingly dependent on digital processing and so require sensors able to provide direct digital inputs. Sensors based on time measurement, having outputs based on a frequency or phase, have an advantage over conventional analogue sensors in that their outputs can be measured directly in digital systems by pulse counting.

A complete design for a data acquisition card for the IBM PC is detailed in this application note. Additionally, C language code is provided to allow sampling of data at speed of more than 20kHz. The speed limitation is strictly based on the execution speed of the "C" data acquisition loop. A "Turbo" XT can acquire data at speeds greater than 20kHz. Machines with 80286 and 80386 processors can go faster than 20kHz. The computer that was used as a test bed in this application was an XT running at 4.77MHz and therefore all system timing and acquisition time measurements are based on a 4.77MHz clock speed.

Sensors for pressure, load, temperature, acceleration andmany other physical quantities often take the form of aWheatstone bridge. These sensors can be extremely linearand stable over time and temperature. However, mostthings in nature are only linear if you don’t bend them toomuch. In the case of a load cell, Hooke’s law states that thestrain in a material is proportional to the applied stress—as long as the stress is nowhere near the material’s yieldpoint (the “point of no return” where the material ispermanently deformed).
