ADR293集成電路（IC）的電壓基準(zhǔn)規(guī)格書PDF中文資料

ADR293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ADR293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 ADR290, ADR291 and ADR292 are low noise, micropower precision voltage references that use an XFET? reference circuit. The new XFET architecture offers significant performance improvements over traditional bandgap and Zener-based references. Improvements include: one quarter the voltage noise output of bandgap references operating at the same current, very low and ultralinear temperature drift, low thermal hysteresis and excellent long-term stability.
