REF02AU/2K5集成电路（IC）的电压基准规格书PDF中文资料

REF02AU/2K5属于集成电路（IC）的电压基准。由德州仪器制造生产的REF02AU/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 REF02 is a precision 5V voltage reference. The drift is

laser trimmed to 10ppm/°C max over the extended industrial

and military temperature range. The REF02 provides a stable

5V output that can be externally adjusted over a ±6% range

with minimal effect on temperature stability. The REF02

operates from a single supply with an input range of 8V to 40V

with a very low current drain of 1mA, and excellent temperature

stability due to an improved design. Excellent line and load

regulation, low noise, low power, and low cost make the

REF02 the best choice whenever a 5V voltage reference is

required. Available package options are DIP-8 and SO-8. The

REF02 is an ideal choice for portable instrumentation,

temperature transducers, Analog-to-Digital (A/D) and Digitalto-

Analog (D/A) converters, and digital voltmeters.
