MC1403 is a precision band-gap voltage reference designed for critical instrumentation and D/A converter applications. This unit is designed to work with D/A converters, up to 12 bits in accuracy, or as a reference for power supply applications. The output voltage is 2.5V with a range of ±25mV, input voltage range is 4.5V to 40V, quiescent current is 1.2mA typical, output current is 10mA, and temperature coefficient is 10ppm/°C typical. It is suitable for voltage reference for 8 to 12 Bit D/A converters, low TC Zener replacement, high stability current reference, and voltmeter system reference.
The MC1403B low‑voltage reference provides a precise 2.5 V output (±25 mV) for instrumentation, D/A converters and power‑supply applications. It operates from an input voltage of 4.5 V to 40 V and draws a typical quiescent current of 1.2 mA while delivering up to 10 mA output current. Its temperature coefficient is 10 ppm/°C typical, giving a guaranteed drift of 7 mV (0 °C‑70 °C) or 12.5 mV (‑40 °C‑85 °C) over the specified range.
The device is offered in standard 8‑pin DIP and SOIC packages, with both standard and Pb‑free versions. Ordering information, package dimensions, and maximum rating tables are provided for designers to select the appropriate variant and ensure reliable operation under the specified environmental limits.
