Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

Overview:

The REF54250CDR Precision Voltage reference is a high-precision, low-drift, low-current consumption series voltage reference device. The REF54 has a low temperature drift coefficient (0.8ppm/°C), low noise (0.11ppmp-p), and high accuracy (±0.02%), while running at a current of only 260µA. With low long-term drift (25ppm) and excellent load and linear adjustment rates, the REF54 helps meet the stringent performance requirements of high-precision applications. The device family is designed as a companion to high-resolution data converters such as the ADS8900B, ADS127L11, ADS1285 and DAC11001B.

The REF54 supports a wide rated supply voltage of 18V. This rating also protects the device in the event of a power IC failure. The REF54 device supports load currents up to 10mA. Wide load current support allows the REF54 to be connected directly to precision sensors as a power source.
