In the future, we will continue to improve the product system and develop more Rectifier Bridge, TPS3809K33DBVR Marking PDBI SOT23 Supervisor and reset ICs, STM32F407ZGT6 Marking STM32F407 LQFP144 single chips and services for different customer groups to meet their needs. In the increasingly competitive market, speed has become a particularly important competitiveness. We focus on customer needs, shorten the R & D cycle, and continue to improve customer satisfaction and production efficiency, to actively create customer trust in us. The company has established the corporate purpose of "being a great enterprise with morality, responsibility, culture, mission and vision" and the corporate mission of "creating value, accumulating wealth, benefiting employees and serving society". Every difficulty that our company has overcome in the process of development depends on all the employees and the company to undertake together, and every progress is also attributed to the efforts of all the employees.
Description
The REF34xx device is a low temperature drift (6 ppm/°C), low-power, high-precision CMOS voltage reference, featuring ±0.05% initial accuracy, low operating current with power consumption less than 95 μA. This device also offers very low output noise of 3.8 μVp-p /V, which enables its ability to maintain high signal integrity with high-resolution data converters in noise critical systems. With a small SOT-23 package, REF34xx offers enhanced specifications and pin-topin replacement for MAX607x, ADR34xx and LT1790 (REF34xxT, no EN pin). The REF34xx family is compatible to most of the ADC and DAC such as ADS1287, DAC8802 and ADS1112.
Stability and system reliability are further improved by the low output-voltage hysteresis of the device and low long-term output voltage drift. Furthermore, the small size and low operating current of the devices (95 μA) benefit portable and battery-powered applications. REF34xx is specified for the wide temperature range of −40°C to +125°C.
