ADR4533ARZ集成電路（IC）的電壓基準(zhǔn)規(guī)格書(shū)PDF中文資料

ADR4533ARZ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ADR4533ARZ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(lèi)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(xiàn)性穩(wěn)壓器相似，但基準(zhǔn)電壓源器件卻不適合用于此類(lèi)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 ADR4520/ADR4525/ADR4530/ADR4533/ADR4540/

ADR4550 devices are high precision, low power, low noise

voltage references featuring ±0.02 B, C, and D grade

maximum initial error, excellent temperature stability, and low

output noise.

This family of voltage references uses an innovative core topology

to achieve high accuracy while offering industry-leading

temperature stability and noise performance. The low, thermally

induced output voltage hysteresis and low long-term output

voltage drift of the devices also improve system accuracy over

time and temperature variations.

A maximum operating current of 950 μA and a maximum low

dropout voltage of 300 mV allow the devices to function very

well in portable equipment.

The ADR4520/ADR4525/ADR4530/ADR4533/ADR4540/

ADR4550 series of references are each provided in an 8-lead

SOIC and are available in a wide range of output voltages, all of

which are specified over the extended industrial temperature

range of ?40°C to +125°C.

The ADR4525, ADR4540, and ADR4550 are also available in D,

which are in 8 lead LCC package, and C grade with a temperature

range of 0°C to 70°C. The ADR4525W, available in an 8-lead

SOIC package, is qualified for automotive applications.
