Using a patented curvature-corrected bandgap architecture with laser-trimmed thin-film resistors, the device achieves excellent stability over temperature. The low 45uA operating current and SLEEP mode (15uA) make it ideal for battery-powered systems. With 30mA output current capability and low dropout, it can drive demanding ADC\/DAC reference loads.","working_principle":"The REF198 uses a curvature-corrected bandgap reference architecture that compensates for the nonlinear temperature characteristics of the basic bandgap cell. Laser-trimmed thin-film resistors ensure precise output voltage calibration and temperature coefficient. A low-dropout output stage allows operation with the input voltage only 100mV above the output. The SLEEP pin, when driven low with a TTL or CMOS signal, disables the output and reduces supply current to 15uA. The output stage includes short-circuit current limiting and thermal shutdown protection.","pin_description":"<table><tr><th>Pin<\/th><th>Name<\/th><th>Type<\/th><th>Function<\/th><\/tr><tr><td>1<\/td><td>VIN<\/td><td>Input<\/td><td>Input supply (4.5-15V)<\/td><\/tr><tr><td>2<\/td><td>GND<\/td><td>Ground<\/td><td>Ground reference<\/td><\/tr><tr><td>3<\/td><td>SLEEP<\/td><td>Input<\/td><td>Sleep mode control (active low)<\/td><\/tr><tr><td>4, 5<\/td><td>NC<\/td><td>-<\/td><td>No connect<\/td><\/tr><tr><td>6<\/td><td>VOUT<\/td><td>Output<\/td><td>4.096V reference output<\/td><\/tr><tr><td>7<\/td><td>GND<\/td><td>Ground<\/td><td>Ground reference<\/td><\/tr><tr><td>8<\/td><td>VIN<\/td><td>Input<\/td><td>Input supply<\/td><\/tr><\/table>","application_scenarios":"<ul><li>Precision ADC reference for data acquisition<\/li><li>DAC voltage reference for control systems<\/li><li>Portable instrument calibration<\/li><li>Solar-powered measurement systems<\/li><li>Smart sensor bias reference<\/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>REF198FSZ<\/td><td>SOIC-8<\/td><td>Higher accuracy grade<\/td><\/tr><tr><td>TI<\/td><td>REF5045IDR<\/td><td>SOIC-8<\/td><td>4.5V reference alternative<\/td><\/tr><tr><td>Maxim<\/td><td>MAX6166ESA+<\/td><td>SOIC-8<\/td><td>4.096V precision reference<\/td><\/tr><tr><td>Microchip<\/td><td>MCP1541T-I\/SN<\/td><td>SOT-23-3<\/td><td>4.096V reference, SOT-23<\/td><\/tr><\/table>"},"_links":{"self":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9884","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=9884"}],"version-history":[{"count":0,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/posts\/9884\/revisions"}],"wp:attachment":[{"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/media?parent=9884"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/categories?post=9884"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/tags?post=9884"},{"taxonomy":"chip_brand","embeddable":true,"href":"https:\/\/materialparts.com\/es\/wp-json\/wp\/v2\/chip_brand?post=9884"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
