The 30pA input bias current and 10^12\u03a9 input resistance make it ideal for high-impedance sensor interfaces. The 1MHz gain-bandwidth product and 3.5V\/\u00b5s slew rate support a wide range of audio and signal conditioning applications. The device is pin-compatible with the TL074 and TL084, providing an easy power-reduction upgrade path. The C-grade operates from 0\u00b0C to +70\u00b0C in an SOIC-14 surface-mount package.","working_principle":"The TL064CDR uses JFET-input differential pairs followed by bipolar gain and output stages. The P-channel JFET input transistors provide the ultra-low 30pA input bias current and 10^12\u03a9 input resistance, allowing direct connection to high-impedance sources without loading. The input JFETs feed a bipolar differential-to-single-ended converter that provides the voltage gain. The output stage is a class-AB push-pull amplifier with short-circuit protection that can source and sink approximately 20mA. Internal compensation provides unity-gain stability with any feedback network. The 200\u00b5A per-amplifier supply current is achieved by reducing the bias current in the gain stages compared to the TL084, trading some bandwidth and slew rate for power savings. The 1MHz GBW means the open-loop gain drops to 0dB at 1MHz, providing approximately 20dB of loop gain at 100kHz \u2014 sufficient for most audio applications.","pin_description":"\n

        TL064CDR is an ultra-low-power quad JFET-input op-amp in SOIC-14 with 1MHz GBW and only 200\u00b5A per amplifier supply current. TL074 and TL084 offer 3MHz GBW at higher supply current for better performance. For single-supply applications, LM324 provides ground-referenced inputs. For low-voltage designs, MCP6004 operates down to 1.8V with rail-to-rail output.<\/p>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/7867","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=7867"}],"version-history":[{"count":1,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/7867\/revisions"}],"predecessor-version":[{"id":8272,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/7867\/revisions\/8272"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=7867"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=7867"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=7867"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=7867"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
