AD780BN集成電路（IC）的電壓基準規(guī)格書PDF中文資料

AD780BN屬于集成電路（IC）的電壓基準。由亞德諾半導體技術(shù)有限公司制造生產(chǎn)的AD780BN電壓基準產(chǎn)品屬于基準電壓源系列，可通過相對較不穩(wěn)定的電源提供穩(wěn)定的電勢，電壓值始終保持恒定，以便在測量、控制和類似應用中用作比較的標準。其功能行為可能與用于大功率調(diào)節(jié)的線性穩(wěn)壓器相似，但基準電壓源器件卻不適合用于此類用途。用作比較標準時，若輸出電流容量或?qū)嶋H負載電流增大，其性能通常會降低。

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.
