Texas Instruments Fixed Series Precision Voltage Reference IC SOIC ±0.05% Surface-Mount 4.1V 8-Pin REF5040AID

Texas Instruments REF5040AID Fixed Series Voltage Reference IC is engineered to deliver highly precise voltage reference levels for demanding electronic applications. With an output of 4.1V and an initial accuracy of ±0.05%, it provides stable and reliable voltage necessary for ADCs, DACs, sensors, and other precision analog circuits. Its low temperature coefficient of 3 ppm/°C ensures the reference stays consistent even as environmental conditions fluctuate.

The device comes in a standard 8-pin SOIC surface-mount package, ideal for space-constrained PCB designs. Supporting a maximum input voltage of 18V and output current up to 10mA, it suits a wide range of circuit designs. The fixed reference output and series topology combine to minimize noise and improve the stability of measurement systems.

REF5040AID operates reliably across a broad temperature window from -40°C up to 125°C, making it suitable for industrial, instrumentation, medical, and communication equipment. Its robust characteristics are further enhanced by line regulation of 1 ppm/V and load regulation of 50 ppm/mA, delivering stable performance under varying load and supply conditions. Automotive applications benefit from its precision, but note it is not classified under automotive standard.

Utilizing surface-mount technology, the IC is easy to integrate into automated assembly processes and is designed for high-density layouts. Its eight pin configuration and small package dimensions - 5mm length and 1.5mm height - make it suitable for integration into complex electronics. With fixed output type and no dynamic adjustment, it helps achieve consistent reference across multiple products or batches.

The REF5040AID is compliant for use in precise signal conditioning, industrial measurement systems, medical equipment, and laboratory instrumentation, serving as a critical component in achieving accurate and repeatable electronic measurements. Its combination of high initial accuracy, reliable thermal stability, and robust electrical parameters make it a preferred choice for engineers seeking reliable voltage references.
