ADR520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ADR520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。

GENERAL DESCRIPTION

Designed for space-critical applications, the ADR520/ADR525/ADR530/ADR540/ADR550 are high precision shunt voltage references, housed in ultrasmall SC70 and SOT-23-3 packages. These references feature low temperature drift of 40 ppm/°C, an initial accuracy of better than ±0.2, and ultralow output noise of 14 μV p-p.
