ADR391BUJZ-REEL7集成電路（IC）的電壓基準(zhǔn)規(guī)格書PDF中文資料

ADR391BUJZ-REEL7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ADR391BUJZ-REEL7電壓基準(zhǔn)產(chǎn)品屬于基準(zhǔn)電壓源系列，可通過相對(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)的線性穩(wěn)壓器相似，但基準(zhǔn)電壓源器件卻不適合用于此類用途。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。

GENERAL DESCRIPTION

The ADR390, ADR391, ADR392, and ADR395 are precision 2.048 V, 2.5 V, 4.096 V, and 5 V band gap voltage references, respectively, featuring low power and high precision in a tiny footprint. Using ADI’s patented temperature drift curvature correction techniques, the ADR39x references achieve a low 9 ppm/°C of temperature drift in the TSOT package.
