Chopperless bipolar input achieves 100dB min CMRR and 112dB open-loop gain without chopper switching noise. 600kHz GBW and 0.3V\/\u00b5s slew rate. \u00b13V to \u00b118V supply range. C suffix denotes commercial temperature (0-70\u00b0C), D suffix denotes SOIC-8, R suffix denotes tape-and-reel. Industry-standard precision DC amplifier since 1975.","working_principle":"The OP07 uses a bipolar input stage with carefully matched super-beta transistors and on-chip trimming to achieve the ultra-low 60\u00b5V max offset voltage. Unlike chopper-stabilized amplifiers, it uses no switching, avoiding the associated switching noise, aliasing, and idle-tone issues. The offset null pins (pins 1 and 8) allow external trimming to zero using a 20k\u03a9 potentiometer for applications requiring even lower offset. The true differential input with high CMRR (100dB min) makes it ideal for bridge and instrumentation amplifier configurations. The internal frequency compensation capacitor provides unity-gain stability without external components.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>OFFSET NULL 1<\/td><td>Adjust<\/td><td>Offset voltage trim terminal 1<\/td><\/tr><tr><td>2<\/td><td>IN-<\/td><td>Input<\/td><td>Inverting input<\/td><\/tr><tr><td>3<\/td><td>IN+<\/td><td>Input<\/td><td>Non-inverting input<\/td><\/tr><tr><td>4<\/td><td>V-<\/td><td>Power<\/td><td>Negative supply (-3V to -18V)<\/td><\/tr><tr><td>5<\/td><td>NC<\/td><td>-<\/td><td>No connect (or OFFSET NULL 2 on some variants)<\/td><\/tr><tr><td>6<\/td><td>OUT<\/td><td>Output<\/td><td>Output<\/td><\/tr><tr><td>7<\/td><td>V+<\/td><td>Power<\/td><td>Positive supply (+3V to +18V)<\/td><\/tr><tr><td>8<\/td><td>OFFSET NULL 2<\/td><td>Adjust<\/td><td>Offset voltage trim terminal 2<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Load cell strain gauge amplifier with 0.01% accuracy<\/li><li>Thermocouple cold junction compensation amplifier<\/li><li>Precision voltage reference buffer with sub-100\u00b5V error<\/li><li>Medical ECG\/EEG front-end amplifier with high CMRR<\/li><li>Lab-grade DC voltage measurement amplifier<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>TI<\/td><td>OPA207DR<\/td><td>SOIC-8<\/td><td>Next-gen, lower power, wider temp<\/td><\/tr><tr><td>TI<\/td><td>OPA202IDR<\/td><td>SOIC-8<\/td><td>Next-gen, heavy capacitive load drive<\/td><\/tr><tr><td>ADI<\/td><td>OP07DRZ<\/td><td>SOIC-8<\/td><td>ADI second source of OP07<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/3379","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=3379"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/3379\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=3379"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=3379"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=3379"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=3379"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
