Precision programmable current source uses two ICs

This Design Idea mates a precision current source IC with precision difference amp chips to create a programmable current source or sink. The resistor-programmable current source/sink in Figure 1 illustrates the basic topology, taking advantage of tightly matched on-chip resistor ratios instead of relying on absolute tolerances. The IIN current source gives rise to a reference voltage across Rf at the op-am ...

Current-sense amp integrates precision shunt resistor, in single package

Texas Instruments says it is making, “high-accuracy measurement more attainable with the first current-sense amplifier to integrate a high-precision, low-drift 2 mΩ shunt resistor,” - the device can cut calibration effort, system cost, and footprint for test and measurement, communications load monitoring, and power supplies. For highly accurate measurements over a wide temperature range, TI’s INA250 integr ...

Fenner Precision Introduces the FHT Class of Synchronous Belts

Manheim, PA (PRWEB) February 5, 2008 Synchronous belts are generally preferred for conveying applications, especially paper propulsion, because they offer higher accuracy, lower maintenance and better performance at higher speeds. Traditionally, these belts have been made of rubber or a composite which doesn't offer the level of tooth definition and precision necessary for many applications. Fenner Precisio ...

Analog Devices Sigma-Delta Converter is Unmatched in Speed and Resolution for Precision Sensing : -ADI’s AD7190 24-bit sigma-delta analog-to-digital converter delivers 7 nV noise and greater than 16-bits noise-free resolution up to 2.4 kHz; also features on-board programmable gain amp.

NORWOOD, Mass. (PRWEB) June 30, 2008 This level of performance allows designers to measure much smaller signals faster and with greater accuracy, which can significantly improve system performance for precision instruments, such as weigh scales, process measurement and control modules, scientific instrumentation and medical monitoring devices. Additionally, designers can achieve an industry-leading 21-bit n ...

Analog Devices’ 16-Bit, 10-MSPS SAR Converter Surpasses Industry Performance Benchmark : – Medical imaging and data acquisition systems gain precision and throughput with PulSAR

NORWOOD, Mass. (PRWEB) June 30, 2008 ADI's AD7626 PulSAR ADC achieves a new level of 16-bit data capture performance, with best-in-class 15-bit ENOB (effective number of bits) and 10-MSPS (million samples per second) throughput, which is 2.5 times faster than other SAR ADCs. Unlike other ADCs, which operate at much lower speeds or reach higher sample rates by increasing power consumption and trading off ac ...

Ultra Precision Industrial Scales with New Technology Introduced By Arlyn Scales

East Rockaway, NY (PRWEB) July 26, 2008 Electronic Industrial Scales are among the most common instruments used throughout a variety of different industries. Industrial engineers and purchasers of electronic scales have two overriding characteristics that they must trade off in their purchasing decision; accuracy and cost. There have traditionally been two predominant technologies that are used by the vast ...
