ADR225HFZ集成電路（IC）的電壓基準規(guī)格書PDF中文資料

ADR225HFZ屬于集成電路（IC）的電壓基準。由亞德諾半導(dǎo)體技術(shù)有限公司制造生產(chǎn)的ADR225HFZ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 ADR225 is a precision 2.5 V band gap voltage reference specified for a high temperature operation of 175°C and 210°C. It uses a micropower core topology and laser trimming of highly stable, thin film resistors to achieve a temperature coefficient of 30 ppm/°C (maximum) up to 175°C and an initial accuracy of 0.4 (±10 mV maximum). A maximum operating current of 50 μA and a low dropout voltage allow the ADR225 to function very well in battery-powered equipment.
