ADR392B集成电路（IC）的电压基准规格书PDF中文资料

ADR392B属于集成电路（IC）的电压基准。由亚德诺半导体技术有限公司制造生产的ADR392B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。

GENERAL DESCRIPTION

The ADR390, ADR391, ADR392, and ADR395 are precision 2.048 V, 2.5 V, 4.096 V, and 5 V band gap voltage references, respectively, featuring low power and high precision in a tiny footprint. Using ADI’s patented temperature drift curvature correction techniques, the ADR39x references achieve a low 9 ppm/°C of temperature drift in the TSOT package.
