LT6654AIS6-3#TRPBF

The LT6654AIS6-3#TRPBF is a precision series voltage reference from Analog Devices, delivering a stable 3.0V output with low noise and high output drive capability in a compact SOT-23-6 package. This family of references accepts a wide supply voltage range reaching 36V and can source or sink up to 10mA, making it well-suited for powering sensor bridges, ADCs, and DACs directly. The LT6654A grade offers tight initial accuracy and a low temperature drift coefficient, typically 10 ppm/°C, preserving accuracy over an industrial temperature range. Its design maintains low dropout voltage and excellent line and load regulation, while the buried Zener architecture ensures low 1/f noise and high long-term stability, critical in high-resolution measurement paths.

Typical applications include precision data acquisition systems, industrial process controls, medical instrumentation, and aerospace avionics where stable voltage references are fundamental to signal integrity. The ‘I’ suffix indicates an operating temperature span of –40°C to +85°C, suitable for rugged industrial equipment and some defense systems that do not require full MIL-STD-883 screening. The device is supplied in tape-and-reel format (TRPBF) for automated surface-mount assembly. Procurement should note that this part is an active product in Analog Devices’ portfolio, minimizing immediate obsolescence risk; however, for designs demanding extended temperature grades or military qualification levels, alternate screening options should be evaluated early in the design cycle to ensure long-term program alignment.
