ADR293GRZ集成電路（IC）的電壓基準(zhǔn)規(guī)格書(shū)PDF中文資料

ADR293GRZ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ADR293GRZ電壓基準(zhǔn)產(chǎn)品屬于基準(zhǔn)電壓源系列，可通過(guò)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 ADR293 is a low noise, micropower precision voltage reference that utilizes an XFET? (eXtra implanted junction FET) reference circuit. The XFET architecture offers significant performance improvements over traditional band gap and buried Zener-based references. Improvements include one quarter the voltage noise output of band gap references operating at the same current, very low and ultralinear temperature drift, low thermal hysteresis, and excellent long term stability.

6.0 V to 15 V supply range

Supply current: 15 μA maximum

Low noise: 15 μV p-p typical (0.1 Hz to 10 Hz)

High output current: 5 mA

Temperature range: ?40°C to +125°C

Pin-compatible with the REF02/REF19x

APPLICATIONS

Portable instrumentation

Precision reference for 5 V systems

ADC and DAC reference

Solar-powered applications

Loop-current powered instruments
