The LinCMOS technology provides 0.6pA typical input bias current, making the device ideal for high-impedance sensor interfaces and sample-and-hold circuits. The 1.8MHz gain-bandwidth product and 3.6V\/\u00b5s slew rate support audio-frequency and moderate-speed applications. The rail-to-rail output swing maximizes dynamic range in single-supply designs. The device operates from 3V to 16V single supply or \u00b11.5V to \u00b18V dual supply, with only 675\u00b5A per amplifier. The C suffix denotes the commercial temperature range (0\u00b0C to +70\u00b0C) and the P suffix denotes the PDIP-8 through-hole package.","working_principle":"The TLC272CP uses TI's LinCMOS (Linear CMOS) process, which combines PMOS input transistors for extremely low input bias current with specialized output stage circuitry for near-rail-to-rail output swing. The input stage uses a differential pair of PMOS transistors, providing the 0.6pA gate leakage current. The input common-mode range extends from the negative rail to approximately VDD - 1.2V, covering most single-supply applications. The output stage uses a common-source PMOS pull-up and NMOS pull-down, allowing the output to swing within tens of millivolts of both supply rails under light load conditions. The internal compensation capacitor provides 48\u00b0 phase margin, ensuring stability in unity-gain configurations without external components. The 1.8MHz GBW means the open-loop gain rolls off at 20dB\/decade from approximately 10Hz, crossing 0dB at 1.8MHz. In a unity-gain configuration, the -3dB bandwidth is 1.8MHz; in a gain of 10 configuration, the bandwidth is approximately 180kHz.","pin_description":"\n

      TLC272CP uses the PDIP-8 package with standard dual op-amp pinout: Pin 1 = Output A, Pin 2 = Inverting Input A (-), Pin 3 = Non-inverting Input A (+), Pin 4 = GND\/VEE, Pin 5 = Non-inverting Input B (+), Pin 6 = Inverting Input B (-), Pin 7 = Output B, Pin 8 = VCC. This pinout is shared by LM358, TL072, NE5532, and all dual op-amps in DIP-8. The CMOS construction provides rail-to-rail output swing and very high input impedance (1T\u03a9 typical). The C suffix denotes commercial temperature range (0\u00b0C to +70\u00b0C). For extended temperature, TLC272IP provides -40\u00b0C to +85\u00b0C. For quad version, TLC274 provides four CMOS op-amps in DIP-14.<\/p>","application_scenarios":"

        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\/7893","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=7893"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/7893\/revisions"}],"predecessor-version":[{"id":8253,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/7893\/revisions\/8253"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=7893"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=7893"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=7893"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=7893"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
