描述 Description

The SG1503 is a monolithic integrated circuit implementing a self-contained precision voltage reference generator. It is internally trimmed for ±1% accuracy and requires less than 2mA quiescent current. SG1503 can deliver greater than 10mA output current while achieving total load and line induced tolerances of less than 0.5%.In addition 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 applications in critical instrumentation and D-to-A converter systems. The SG1503 is specified for operation over the full military ambient temperature range of -55°C to 125°C, while the SG2503 is designed for -25°C to 85°C and the SG3503 for commercial applications of 0°C to 70°C.

SG3503屬于集成電路（IC）的電壓基準(zhǔn)。由制造生產(chǎn)的SG3503電壓基準(zhǔn)產(chǎn)品屬于基準(zhǔn)電壓源系列，可通過(guò)相對(duì)較不穩(wěn)定的電源提供穩(wěn)定的電勢(shì)，電壓值始終保持恒定，以便在測(cè)量、控制和類似應(yīng)用中用作比較的標(biāo)準(zhǔn)。其功能行為可能與用于大功率調(diào)節(jié)的線性穩(wěn)壓器相似，但基準(zhǔn)電壓源器件卻不適合用于此類用途。用作比較標(biāo)準(zhǔn)時(shí)，若輸出電流容量或?qū)嶋H負(fù)載電流增大，其性能通常會(huì)降低。
