The device features an exceptionally low 1.0 Ohm typical on-resistance with 0.2 Ohm flatness across the analog input range, making it ideal for precision signal routing where signal integrity is critical. The switch handles rail-to-rail analog signals with supply voltages from +\/-5V to +\/-15V dual supply or +12V single supply. The 800MHz bandwidth supports high-frequency applications. Charge injection is only -5pC typical, minimizing signal perturbation during switching transitions. The device is available in a compact MSOP-10 package suitable for space-constrained designs.","working_principle":"The ADG1421BRMZ is a single-channel analog switch using iCMOS technology. (1) Switch Structure: The switch uses a parallel N-channel and P-channel MOSFET pair. When the IN control pin is logic high, both MOSFETs are turned on, providing a low-impedance path between S and D terminals. The complementary structure ensures flat Ron across the full signal range from VSS to VDD. (2) Low Ron: Large-geometry MOSFETs in the iCMOS process achieve the 1.0 Ohm typical on-resistance. (3) Charge Injection: The -5pC charge injection is achieved by carefully matching the N-channel and P-channel gate charge contributions, which partially cancel each other.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>S<\/td><td>Source terminal<\/td><\/tr><tr><td>2<\/td><td>D<\/td><td>Drain terminal<\/td><\/tr><tr><td>3<\/td><td>VSS<\/td><td>Negative supply<\/td><\/tr><tr><td>4<\/td><td>GND<\/td><td>Ground<\/td><\/tr><tr><td>5<\/td><td>IN<\/td><td>Control input (high=on)<\/td><\/tr><tr><td>6<\/td><td>VDD<\/td><td>Positive supply<\/td><\/tr><tr><td>7-10<\/td><td>NC<\/td><td>No connect<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Precision signal routing with 1 Ohm Ron and 800MHz bandwidth<\/li><\/ul>","alternative_models":"<table><tr><th>Manufacturer<\/th><th>Part Number<\/th><th>Package<\/th><th>Notes<\/th><\/tr><tr><td>ADI<\/td><td>ADG1422BRMZ<\/td><td>MSOP-10<\/td><td>NC (normally closed) version<\/td><\/tr><tr><td>ADI<\/td><td>ADG1411BRMZ<\/td><td>MSOP-10<\/td><td>1.5 Ohm, quad switch<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/7342","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/comments?post=7342"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/posts\/7342\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/media?parent=7342"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/categories?post=7342"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/tags?post=7342"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/zh\/wp-json\/wp\/v2\/chip_brand?post=7342"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
