SG1503/SG2503/SG3503

Precision 2.5-Volt Reference

Description

Features

The SG1503 is

implementing

monolithic integrated circuit

Output Voltage Trimmed to ±1%

self-contained precision voltage

Input Voltage Range of 4.5V to 40V

Temperature Coefficient of 10ppm/°C

Quiescent Current Typically 1.5mA

Output Current in excess of 10mA

Interchangeable with MC1503 and AD580

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%.

Application

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.
