Designed to operate from a single power supply over a wide range of voltages (3V to 32V), it can also operate from split supplies. The device features low power consumption, making it suitable for battery-powered applications. Each amplifier has a typical gain bandwidth product of 1.2 MHz and a slew rate of 0.5 V\/us, providing adequate performance for most general-purpose signal conditioning applications.","working_principle":"The LM224DR integrates four independent op-amps, each employing a standard voltage-feedback architecture. **Input Stage**: A differential pair with PNP transistors provides the wide common-mode input range that includes ground (in single-supply operation). The input bias current is typically 45 nA flowing out of the input pins. **Gain Stage**: A high-gain voltage amplifier stage with internal compensation capacitor provides a gain-bandwidth product of 1.2 MHz and ensures unconditional stability with unity-gain feedback. **Output Stage**: A Class AB push-pull output stage can source and sink tens of milliamps, with short-circuit current limiting. The output swings to within approximately 1.5V of the negative rail under load. **Bias Network**: A shared bias network across all four amplifiers minimizes total quiescent current.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Description<\/th><\/tr><tr><td>1<\/td><td>OUT A<\/td><td>Channel A Output<\/td><\/tr><tr><td>2<\/td><td>IN- A<\/td><td>Channel A Inverting Input<\/td><\/tr><tr><td>3<\/td><td>IN+ A<\/td><td>Channel A Non-Inverting Input<\/td><\/tr><tr><td>4<\/td><td>VCC<\/td><td>Positive Supply Voltage<\/td><\/tr><tr><td>5<\/td><td>IN+ B<\/td><td>Channel B Non-Inverting Input<\/td><\/tr><tr><td>6<\/td><td>IN- B<\/td><td>Channel B Inverting Input<\/td><\/tr><tr><td>7<\/td><td>OUT B<\/td><td>Channel B Output<\/td><\/tr><tr><td>8<\/td><td>OUT C<\/td><td>Channel C Output<\/td><\/tr><tr><td>9<\/td><td>IN- C<\/td><td>Channel C Inverting Input<\/td><\/tr><tr><td>10<\/td><td>IN+ C<\/td><td>Channel C Non-Inverting Input<\/td><\/tr><tr><td>11<\/td><td>GND \/ VEE<\/td><td>Negative Supply \/ Ground<\/td><\/tr><tr><td>12<\/td><td>IN+ D<\/td><td>Channel D Non-Inverting Input<\/td><\/tr><tr><td>13<\/td><td>IN- D<\/td><td>Channel D Inverting Input<\/td><\/tr><tr><td>14<\/td><td>OUT D<\/td><td>Channel D Output<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Signal Conditioning: Low-frequency transducer amplifiers for sensor interfaces in industrial control<\/li><li>Active Filters: Multiple 2nd-order filter stages using a single IC for audio or instrumentation<\/li><li>DC Gain Blocks: Instrumentation front-end amplifiers with single-supply operation down to 3V<\/li><li>Comparators: Open-loop voltage comparison for threshold detection in monitoring circuits<\/li><li>Oscillators: RC oscillators and waveform generators for timing and clock generation<\/li><\/ul>","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Difference<\/th><\/tr><tr><td>LM324DR<\/td><td>TI<\/td><td>Extended temp range 0C to 70C<\/td><\/tr><tr><td>LM2902DR<\/td><td>TI<\/td><td>Automotive grade, -40C to 125C<\/td><\/tr><tr><td>MCP6004T-I\/SL<\/td><td>Microchip<\/td><td>RRIO, 1.8V-6V, lower power<\/td><\/tr><tr><td>TLV274IPWR<\/td><td>TI<\/td><td>RRIO, 2.7V-16V, 3MHz GBW<\/td><\/tr><tr><td>OPA4340UA<\/td><td>TI<\/td><td>RRIO, 2.5V-5.5V, 5.5MHz GBW<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6239","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/comments?post=6239"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6239\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=6239"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=6239"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=6239"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=6239"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
