GENERAL DESCRIPTION

The REF02 precision voltage reference providesa stable5 V output that can be adjustedover a ±6 range with minimal effect on temperature stability. Single-supply operation over an input voltage range of7 V to40 V,low current drain of1 mA, and excellent temperature stability are achieved with an improved band gap design. Low cost, low noise,and low power make the REF02 anexcellent choice when ever a stable voltage reference is required. Applications include DACs and ADCs, portable instrumentation, and digital volt meters. The versatility ofthe REF02 is enhanced byits use as a monolithic temperature transducer. For new designs, refer to the ADR02.

REF02EJ属于集成电路（IC） > 电压基准。亚德诺半导体技术有限公司制造生产的REF02EJ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。
