AN-300 Simple Circuit Detects Loss of 4-20 mA Signal (Rev. B)
Texas InstrumentsFour-to-twenty milliampere current loops are commonly used in the process control industry. They takeadvantage of the fact that a remote amplifier can be powered by the same 4-20 mA current that it controlsas its output signal thus using a single pair of wires for signal and power. Circuits for making 4-20 mAtransmitters are found in the LM10 LM163 and LH0045 data sheets.
UC3717 and L-C Filter Reduce EMI and Chopping Losses in Step Motor
Texas InstrumentsThe UC3717 stepper motor drive circuit controls and drives the current in one winding of a bipolar stepper motor. A chopper drive that uses the inductance of the motor as the controlling element causes a temperature rise in the motor because of hysteresis and eddy current losses. This application note explains how to solve that problem by placing a properly designed low-pass L-C filter across the

AC Coupling Instrumentation and Difference Amplifiers
Texas InstrumentsThe need to glean AC signals from DC in the presence of common-mode noise frequently occurs in signal conditioning applications. AC coupling to an instrumentation amplifier (IA) or difference amplifier can be used to accurately extract the AC signal while rejecting DC and common-mode noise.

Clock jitter analyzed in the time domain, Part 1
Texas InstrumentsNewer high-speed ADCs come outfitted with a large analog-input bandwidth (about three to six times the maximum sampling frequency) so they can be used in undersampling applications. Recent advances in ADC design extend the usable input range significantly so that system designers can eliminate at least one intermediate frequency stage, which reduces cost and power consumption. In the design of an undersampling receiver, special attention has to be given to the sampling clock, because at higher input frequencies the jitter of the clock becomes a dominant factor in limiting the signal-to-noise ratio (SNR).
Part 1 of this three-part article series focuses on how to accurately estimate jitter from a clock source and combine it with the aperture jitter of the ADC. In Part 2, that combined jitter will be used to calculate the ADC’s SNR, which will then be compared against actual measurements. Part 3 will show how to further increase the SNR of the ADC by improving the ADC’s aperture jitter, with a focus on optimizing the slew rate of the clock signal.
U-113 Design Notes on Precision Phase Locked Speed Control for DC Motors
Texas InstrumentsThe UC3633 family of integrated circuits is for use in phase-locked frequency control loops. There are a number of high volume applications for DC motors that require precision control of the motor's speed. Phase-locked loop techniques are well suited to provide this control by phase-locking the motor to a stable and accurate reference frequency. This application note discusses the small-signal ch
