It combines a 10 MHz gain-bandwidth product with low 9 nV\/\u221aHz voltage noise density, making it suitable for audio and sensor signal conditioning where both bandwidth and noise performance are critical. The 930 \u00b5A per-channel supply current is modest for a 10 MHz amplifier, providing a favorable GBW-to-power ratio. The bipolar input stage delivers low noise and high CMRR (89 dB typical), while the rail-to-rail output stage maximizes dynamic range in single-supply applications. The input common-mode range includes ground, enabling direct sensing of ground-referenced signals. The MX suffix indicates SOIC-8 packaging.","working_principle":"The LMV722MX uses a BiCMOS process that combines a bipolar input stage with CMOS output stage circuitry. The bipolar input differential pair provides low voltage noise (9 nV\/\u221aHz) and high transconductance, enabling the 10 MHz gain-bandwidth product with moderate supply current. The input common-mode range extends 0.3V below the negative rail through a complementary PNP\/NPN input pair arrangement. The CMOS rail-to-rail output stage uses complementary PMOS\/NMOS transistors in a common-source configuration, allowing the output to swing within 50 mV of each supply rail under 2k\u03a9 load. Internal compensation ensures stability with unity-gain feedback. The bipolar input stage contributes a 260 nA typical bias current, which is higher than CMOS-input alternatives but provides superior noise performance.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>OUT A<\/td><td>Amplifier A output<\/td><\/tr><tr><td>2<\/td><td>-IN A<\/td><td>Amplifier A inverting input<\/td><\/tr><tr><td>3<\/td><td>+IN A<\/td><td>Amplifier A non-inverting input<\/td><\/tr><tr><td>4<\/td><td>GND<\/td><td>Negative supply \/ Ground<\/td><\/tr><tr><td>5<\/td><td>+IN B<\/td><td>Amplifier B non-inverting input<\/td><\/tr><tr><td>6<\/td><td>-IN B<\/td><td>Amplifier B inverting input<\/td><\/tr><tr><td>7<\/td><td>OUT B<\/td><td>Amplifier B output<\/td><\/tr><tr><td>8<\/td><td>V+<\/td><td>Positive supply (2.2-5.5V)<\/td><\/tr><\/table>","application_scenarios":"The LMV722MX excels in audio signal paths where the 9 nV\/\u221aHz noise density preserves signal integrity from low-level microphone or line-level sources. In cellular phones, the 10 MHz bandwidth supports anti-aliasing filters for voice-band and audio CODEC interfaces. For active filter applications, the GBW product supports filter topologies up to several hundred kHz with reasonable Q factors. In laptop audio subsystems, the rail-to-rail output and ground-including input simplify single-supply designs. The 0.004% THD at 1 kHz makes it transparent in audio signal chains.","alternative_models":"<table><tr><th>Model<\/th><th>Manufacturer<\/th><th>Key Difference<\/th><\/tr><tr><td>LMV722MM\/NOPB<\/td><td>Texas Instruments<\/td><td>VSSOP-8 package, same specs<\/td><\/tr><tr><td>NE5532DR<\/td><td>Texas Instruments<\/td><td>Dual, 10MHz, 5nV\/\u221aHz, \u00b122V<\/td><\/tr><tr><td>OPA2340EA<\/td><td>Texas Instruments<\/td><td>5.5MHz, CMOS input, 0.5pA Ibias<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6514","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=6514"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/posts\/6514\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/media?parent=6514"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/categories?post=6514"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/tags?post=6514"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/ar\/wp-json\/wp\/v2\/chip_brand?post=6514"}],"curies":[{"name":"\u062f\u0628\u0644\u064a\u0648 \u0628\u064a","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
