LT1004CDR-2-5集成电路（IC）的电压基准规格书PDF中文资料

LT1004CDR-2-5属于集成电路（IC）的电压基准。由德州仪器制造生产的LT1004CDR-2-5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。

− Battery-Operated Systems

− Current-Loop Instrumentation

description/ordering information

The LT1004 micropower voltage reference is a

two-terminal band-gap reference diode designed

to provide high accuracy and excellent

temperature characteristics at very low operating

currents. Optimizing the key parameters in the

design, processing, and testing of the device

results in specifications previously attainable only

with selected units.

The LT1004 is a pin-for-pin replacement for the LM285 and LM385 series of references, with improved

specifications. It is an excellent device for use in systems in which accuracy previously was attained at the

expense of power consumption and trimming.

The LT1004C is characterized for operation from 0°C to 70°C. The LT1004I is characterized for operation from

−40°C to 85°C.
