REF1004I-2.5/2K5集成电路（IC）的电压基准规格书PDF中文资料

REF1004I-2.5/2K5属于集成电路（IC）的电压基准。由德州仪器制造生产的REF1004I-2.5/2K5电压基准产品属于基准电压源系列，可通过相对较不稳定的电源提供稳定的电势，电压值始终保持恒定，以便在测量、控制和类似应用中用作比较的标准。其功能行为可能与用于大功率调节的线性稳压器相似，但基准电压源器件却不适合用于此类用途。用作比较标准时，若输出电流容量或实际负载电流增大，其性能通常会降低。

DESCRIPTION

The REF1004-1.2 and REF1004-2.5 are two terminal

bandgap reference diodes designed for high accuracy

with outstanding temperature characteristics at low

operating currents. Prior to the introduction of the

REF1004 Micropower Voltage References, accuracy

and stability specifications could only be attained by

expensive screening of standard devices. The REF1004

is a cost effective solution when reference voltage

accuracy, low power, and long term temperature stability

are required.

REF1004 is a drop-in replacement for the LT1004 as

well as an upgraded replacement of the LM185/385

series references. The REF1004C is characterized for

operation from 0°C to 70°C and the REF1004I is

characterized for operation from –40°C to +85°C.

The REF1004 is offered in an 8-lead Plastic SOIC

package and shipped in anti-static rails or tape and

reel.
