MCP1502中文资料High Precision Buffered Voltage Reference数据手册Microchip规格书

描述 Description

The MCP1502 is a high-precision buffered voltage reference with an initial accuracy of 0.10% and is available in 10 voltage options. The MCP1502 is a low-drift (7ppm max) bandgap-based reference and uses chopper-based amplifiers which significantly reduces the drift and provides high current output. The MCP1502 is available in the SOT-23 package and comes with Grade 1 AEC-Q100 qualifications.

简介

MCP1502属于集成电路（IC）的电压基准。由Microchip制造生产的MCP1502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。
