MAX6194CESA+

The MAX6194CESA+ is a micropower, low dropout, adjustable voltage reference designed specifically for portable electronic devices. The MAX6194CESA+ is available in an ultra-small, 1.6mm × 1.6mm Thin ThinQ package making it specifically well suited for space-constrained portable designs. It features an ENABLE pin that can be used to reduce supply current when the reference is not needed. Other features such as low input-voltage operation and a wide adjustment range make the MAX6194CESA+ an easy-to-use, high accuracy reference.

Application Field

In portable electronic devices, it is necessary to use voltage references that are not only accurate, but also have low current consumption. The MAX6194CESA+ is a micropower, low dropout, adjustable voltage reference especially designed for these applications. It features an enable pin that can be used to further reduce current consumption when the reference is not needed. It packed in a compact 1.6mm×1.6mm Thin ThinQ package which makes it suitable for ultra-small portable designs.

MAX6194CESA+ can be used in a variety of portable devices such as battery-operated smartphones, cameras, hand-held devices, portable medical equipment, and wearable technology. Additionally, it can be used in any application that requires low voltage and high accuracy reference.

Working Principle

The MAX6194CESA+ is a micropower, low dropout, adjustable voltage reference featuring truly low power consumption. Its supply current is typically only 1.7μA at 5VIN, an industry-leading supply current. The device operates with an input voltage range of 1.8V to 5.5V, making it well suited for battery-operated or power-sensitive applications.

A unique ENABLE pin features can be used to reduce the supply current by 97%. This reduces the supply current to 0.05μA when the reference is not needed. The device offers an input-voltage-independent output accuracy of ±2% and full-scale output voltage range of 2.0V to 21V.

The MAX6194CESA+ provides excellent noise performance and is temperature stable, allowing for both excellent power-supply ripple rejection and accurate output voltage setting. The device also features a three-pin configuration that makes it easier to integrate into new or existing designs.

Conclusion

The MAX6194CESA+ is an ideal voltage reference for portable electronic device applications. It provides an ultra-small, 1.6mm×1.6mm Thin ThinQ package and an ENABLE pin that can reduce supply current when the reference is not needed, making it suitable for space-constrained designs. The device offers an input-voltage-independent output accuracy of ±2% and a wide adjustment range, making it an easy-to-use, high accuracy reference.
