ADR540集成电路（IC）的电压基准规格书PDF中文资料

ADR540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ADR540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

Designed for space-critical applications, the ADR520/ADR525/ADR530/ADR540/ADR550 are high precision shunt voltage references, housed in ultrasmall SC70 and SOT-23-3 packages. These references feature low temperature drift of 40 ppm/°C, an initial accuracy of better than ±0.2, and ultralow output noise of 14 μV p-p.
