SG3503M中文资料Voltage References数据手册Microchip规格书

描述 Description

Key Features:
• Output voltage trimmed to ±1%
• Input voltage range of 4.5 to 40V
• Temperature coefficent of 10ppm/°C
• Quiescent current typically 1.5mA
• Output current in excess of 10mA
• Interchangeable with MC1503 and AD580This monolithic integrated circuit is a fully self-contained precision voltage reference generator, internally trimmed for ±1% accuracy. Requiring less than 2mA in quiescent current, this device can deliver in excess of 10mA with total load- and line-induced tolerances of less than 0.5%. In additon to voltage accuracy, internal trimming achieves a temperature coefficient of output voltage of typically 10 ppm/C. As a result, these references are excellent choices for application to critical instrumentation and D-to-A converter systems.The SG1503 is specified for operation over the full military ambient temperature range of -55C to 125C , while the SG2503 is designed for -25C to 85C and the SG3503 for commercial applications of 0C to 70C.

简介

SG3503M属于集成电路（IC）的电压基准。由制造生产的SG3503M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。
