The device operates from a single 3V to 16V supply and features rail-to-rail output swing that reaches within 10mV of the supply rails under light loads. The 1pA typical input bias current makes it ideal for high-impedance sensor interfaces. The 1.1MHz gain-bandwidth product and 3.5V\/\u00b5s slew rate support a wide range of signal conditioning applications. Phase-reversal protection prevents output inversion when the input common-mode range is exceeded. The A-grade offers 800\u00b5V typical input offset voltage.","working_principle":"The TLC272ACDR uses TI's LinCMOS process, which combines PMOS input differential pairs with a CMOS output stage. The PMOS input transistors provide the ultra-low 1pA input bias current and very high input impedance, enabling direct connection to high-impedance sensors and capacitive sources. The input common-mode range extends from -0.2V below the negative rail to approximately VDD-1.2V, limited by the tail current source of the differential pair. The gain stage uses a folded-cascode architecture for high gain and wide bandwidth. The output stage is a class-AB CMOS push-pull that swings rail-to-rail, reaching within 10mV of both supply rails at light loads. The internal compensation capacitor provides unity-gain stability with any capacitive load. Phase-reversal protection circuitry prevents the output from changing sign when the input is driven beyond the common-mode range, a common failure mode of older CMOS op-amps. The 675\u00b5A per-amplifier supply current reflects the bias current needed to achieve the 1.1MHz GBW.","pin_description":"\n

        TLC272 is a dual CMOS rail-to-rail output op-amp with 1.8MHz GBW and 3-16V supply range. The AC-grade offers tighter offset specifications. For lower-voltage designs, MCP6002 operates down to 1.8V. For ultra-low-power battery applications, TLV2322 draws only 2\u00b5A per amplifier. The TLC272 is ideal for single-supply signal conditioning where input common-mode range includes ground.<\/p>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/7844","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/comments?post=7844"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/7844\/revisions"}],"predecessor-version":[{"id":8291,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/7844\/revisions\/8291"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=7844"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=7844"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=7844"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=7844"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
