AD780BR-REEL7集成电路（IC）的电压基准规格书PDF中文资料

AD780BR-REEL7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AD780BR-REEL7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。

PRODUCT DESCRIPTION

The AD780 is an ultrahigh precision band gap reference voltage that provides a 2.5 V or 3.0 V output from inputs between 4.0 V and 36 V. Low initial error and temperature drift combined with low output noise and the ability to drive any value of capacitance make the AD780 the ideal choice for enhancing the performance of high resolution ADCs and DACs, and for any general-purpose precision reference application. A unique low headroom design facilitates a 3.0 V output from a 5.0 V 10 input, providing a 20 boost to the dynamic range of an ADC over performance with existing 2.5 V references.
