AD680集成電路（IC）的電壓基準規(guī)格書PDF中文資料

AD680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AD680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(yīng)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

The AD680 is a band gap voltage reference that provides a fixed 2.5 V output from inputs between 4.5 V and 36 V. The architecture of the AD680 enables the reference to be operated at a very low quiescent current while still realizing excellent dc characteristics and noise performance. Trimming of the high stability thin-film resistors is performed for initial accuracy and temperature coefficient, resulting in low errors over temperature.

FEATURES
