REF102AU/2K5集成电路（IC）的电压基准规格书PDF中文资料

REF102AU/2K5属于集成电路（IC）的电压基准。由德州仪器制造生产的REF102AU/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 REF102 is a precision 10V voltage reference. The drift

is laser-trimmed to 2.5ppm/°C max C-grade over the industrial

temperature range. The REF102 achieves its precision

without a heater. This results in low power, fast warm-up,

excellent stability, and low noise. The output voltage is

extremely insensitive to both line and load variations and can

be externally adjusted with minimal effect on drift and

stability. Single-supply operation from 11.4V to 36V and

excellent overall specifications make the REF102 an ideal

choice for demanding instrumentation and system reference

applications.
