TI REF54300CDR

REF54 is a series of high-precision, low-drift, low-current-consumption series voltage reference devices. The REF54 series offers a low temperature coefficient (0.8ppm/°C), low noise (0.11ppmp-p), and high accuracy (±0.02%), while consuming 380μA. The REF54 features low long-term drift (3ppm LCCC; 25ppm SOIC) and excellent load and line regulation, helping to meet the stringent performance requirements of high-precision applications. This 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 supply voltage range of 18V. REF54 devices support load currents up to 10mA. The REF54 is available in two temperature ranges: grade C for 0°C to 70°C, and grade Q for -40°C to +125°C. The wide temperature range makes it suitable for a variety of industrial applications.
