DS4303R-U+

The DS4303R-U+ is a nonvolatile, electronically programmable voltage reference manufactured by Maxim Integrated. This device allows for precise, in-circuit adjustment of the reference voltage during factory calibration or programming. The voltage level can be locked indefinitely, even after power cycles, thanks to its non-volatile memory.

Key features include a wide adjustable output voltage range within 300mV of the supply rails, with an adjustment accuracy of ±1mV. It provides ±1mA of output current drive and boasts a low temperature coefficient. The device operates from a 2.4V to 3.6V single supply and includes output short-circuit protection.

Packaged in a compact 5-lead SOT23 surface-mount package, the DS4303R-U+ is designed for applications requiring automated factory trimming and flexible manufacturing arrangements. Its low cost and low power consumption make it suitable for power-supply calibration, threshold setting, offset nulling, and bias adjusting in various electronic equipment.

The DS4303R-U+ replaces traditional, cumbersome factory adjustment methods with a low-cost, automated solution, enabling quicker time-to-market and potentially lower inventory costs.
