ADS-939 Sampling A/D Converter Delivers True 16-Bit Performance at 10MHz in a Fully Integrated Package

  • 16-bit resolution
  • 10MHz sampling rate
  • Functionally complete
  • No missing codes over full military temperature range
  • Edge-triggered
  • ±5V, ±12V or ±15V supplies, 3.0 Watts
  • Small, 40-pin, ceramic TDIP
  • 82dB SNR, -86dB THD
  • Ideal for both time and frequency-domain applications
DATEL The ADS-939 sampling A/D converter is a fully integrated data acquisition system that gives true 16-bit resolution performance at a 10MHz sampling rate over the entire operating temperature range, up to full Military. The functionally complete design requires no external components and is housed in a small, high reliability, hermetically sealed, 40-pin ceramic TDIP.

Typical applications include medical imaging, radar, sonar, communications and instrumentation.

The rising edge triggered ADS-939 is ideal for use in both time and frequency domain applications. It accurately samples full-scale input signals with no missing codes up to Nyquist frequencies and across the full operating temperature range. The dynamic performance of the new device has been optimized to give a high signal-to-noise (SNR) ratio of 82dB and total harmonic distortion (THD) of -86dB at Nyquist input frequency.

Able to operate from a ±5V, ±12V or ±15V supply, the ADS-939 dissipates just 1.5 Watts - half the power consumption of the ADS-935 (16-bit, 5MHz) A/D converter for which it is a pin-for-pin replacement. The new device is offered with a bipolar (±2.75V) or a unipolar (0V to -5.5V) analog input range.

Variants are available to address applications with both commercial (OºC to +70ºC) and military (-55ºC to +125ºC) temperature ranges.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
