{"product_id":"hcpl-7840-smd-optocoupler-in-pakistan","title":"Hcpl 7840 Hcpl-7840 Isolated Amplifier For Current Sensing","description":"\u003cp\u003eThe HCPL-7840 isolation amplifier family was designed for current sensing in electronic motor drive applications. In a typical implementation, motor currents flow through an external resistor and the resulting analog voltage drop is sensed by the HCPL-7840. A differential output voltage is created on the other side of the HCPL-7840 optical isolation barrier. This differential output voltage is proportional to the motor current and can be converted to a single-ended signal by using an op-amp.\u003cbr\u003e\r\n\u003cbr\u003e\r\nSince common-mode voltage swings of several hundred volts in tens of nanoseconds are common in modern switching inverter motor drives, the HCPL-7840 was designed to ignore very high common-mode transient slew rates (of at least 10 kV\/ms).\u003c\/p\u003e\r\n\r\n\u003cp\u003eThe high CMR capability of the HCPL-7840 isolation amplifier provides the precision and stability needed to accurately monitor motor current in high noise motor control environments, providing for smoother control (less \"torque ripple\") in various types of motor control applications.\u003c\/p\u003e\r\n\r\n\u003cp\u003eThe product can also be used for general analog signal isolation applications requiring high accuracy, stability, and linearity under similarly severe noise conditions. For general applications, we recommend the HCPL-7840 (gain tolerance of \/- 5%). The HCPL-7840 utilizes sigma delta (S-D) analog-to-digital converter technology, chopper stabilized amplifiers, and a fully differential circuit topology fabricated using Broadcom'ss 0.8 mm CMOS IC process.\u003c\/p\u003e\r\n\r\n\u003cp\u003eTogether, these features deliver unequaled isolation-mode noise rejection, as well as excellent offset and gain accuracy and stability over time and temperature. This performance is delivered in a compact, auto-insertable, industry standard 8-pin DIP package that meets worldwide regulatory safety standards. (A gull-wing surface mount option #300 is also available).\u003c\/p\u003e\r\n\r\n\u003ch2\u003eApplications:\u003c\/h2\u003e\r\n\r\n\u003cul\u003e\r\n\t\u003cli\u003eMotor Phase and Rail Current Sensing\u003c\/li\u003e\r\n\t\u003cli\u003eInverter Current Sensing\u003c\/li\u003e\r\n\t\u003cli\u003eDC Bus Voltage Sensing\u003c\/li\u003e\r\n\t\u003cli\u003eSwitched Mode Power Supply Signal Isolation\u003c\/li\u003e\r\n\t\u003cli\u003eGeneral Purpose Current Sensing and Monitoring\u003c\/li\u003e\r\n\t\u003cli\u003eGeneral Purpose Analog Signal Isolation\u003c\/li\u003e\r\n\t\u003cli\u003eTraditional Hall Effect Sensor Replacement\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003ch1\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/h1\u003e\r\n\r\n\u003cul\u003e\r\n\t\u003cli\u003e15 kV\/ms Common-Mode Rejection at VCM = 1000 V\u003c\/li\u003e\r\n\t\u003cli\u003eCompact, Auto-Insertable Standard 8-pin DIP Package\u003c\/li\u003e\r\n\t\u003cli\u003e0.00025 V\/V\/ degrees C Gain Drift vs. Temperature\u003c\/li\u003e\r\n\t\u003cli\u003e0.3 mV Input Offset Voltage\u003c\/li\u003e\r\n\t\u003cli\u003e100 kHz Bandwidth\u003c\/li\u003e\r\n\t\u003cli\u003e0.004% Nonlinearity\u003c\/li\u003e\r\n\t\u003cli\u003eWorldwide Safety Approval: UL 1577 (3750 Vrms\/1 min.) and CSA (pending), IEC\/EN\/DIN EN 60747-5-2 (option 060 only)\u003c\/li\u003e\r\n\t\u003cli\u003eAdvanced Sigma-Delta (S-D) A\/D Converter Technology\u003c\/li\u003e\r\n\t\u003cli\u003eFully Differential Circuit Topology\u003c\/li\u003e\r\n\t\u003cli\u003e0.8 mm CMOS IC Technology\u003c\/li\u003e\r\n\t\u003cli\u003eOptions available are:\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\r\n\u003cp\u003eNo Option = Standard DIP package, 50 per tube\u003cbr\u003e\r\n060 = IEC\/EN\/DIN EN 60747-5-2 Option\u003cbr\u003e\r\n300 = Surface Mount Option\u003cbr\u003e\r\n500 = Tape\/Reel Packaging Option, 1 k min. per reel\u003cbr\u003e\r\nXXXE = Lead Free Option\u003c\/p\u003e\r\n\r\n\u003ch2\u003ePackage Includes:\u003c\/h2\u003e\r\n\r\n\u003ch3\u003e1XHCPL 7840 Smd Optocoupler\u003cstrong\u003ePackage Include:\u003c\/strong\u003e\n\u003c\/h3\u003e\r\n","brand":"Digilog Electronics","offers":[{"title":"Default Title","offer_id":43962382319681,"sku":"DELL,B163","price":330.0,"currency_code":"PKR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0727\/2805\/1777\/files\/HCPL-7840_wht_result.jpg?v=1779572832","url":"https:\/\/stem.pk\/products\/hcpl-7840-smd-optocoupler-in-pakistan","provider":"stem.pk","version":"1.0","type":"link"}
