AD780BNZ集成電路（IC）的電壓基準(zhǔn)規(guī)格書(shū)PDF中文資料

AD780BNZ屬于集成電路（IC）的電壓基準(zhǔn)。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的AD780BNZ電壓基準(zhǔn)產(chǎn)品屬于基準(zhǔn)電壓源系列，可通過(guò)相對(duì)較不穩(wěn)定的電源提供穩(wěn)定的電勢(shì)，電壓值始終保持恒定，以便在測(cè)量、控制和類(lèi)似應(yīng)用中用作比較的標(biāo)準(zhǔn)。其功能行為可能與用于大功率調(diào)節(jié)的線(xiàn)性穩(wěn)壓器相似，但基準(zhǔn)電壓源器件卻不適合用于此類(lèi)用途。用作比較標(biāo)準(zhǔn)時(shí)，若輸出電流容量或?qū)嶋H負(fù)載電流增大，其性能通常會(huì)降低。

PRODUCT DESCRIPTION

The AD780 is an ultrahigh precision band gap reference voltage that provides a 2.5 V or 3.0 V output from inputs between 4.0 V and 36 V. Low initial error and temperature drift combined with low output noise and the ability to drive any value of capacitance make the AD780 the ideal choice for enhancing the performance of high resolution ADCs and DACs, and for any general-purpose precision reference application. A unique low headroom design facilitates a 3.0 V output from a 5.0 V 10 input, providing a 20 boost to the dynamic range of an ADC over performance with existing 2.5 V references.
