LT6658 Precision Dual Output, High Current, Low Noise, Voltage Reference Description

The LT6658 precision 2.5V dual output reference combines the performance of a low drift low noise reference and a linear regulator. Both outputs are ideal for driving the precision reference inputs of high resolution ADCs and DACs, even with heavy loading while simultaneously acting as output supplies powering microcontrollers and other supporting devices. Both outputs have the same precision specifications and track each other over temperature and load. Both outputs are nominally 2.5V, however each can be configured with external resistors to give an output voltage to 6V. Using Kelvin connections, the LT6658 typically has 0.1ppm/mA load regulation with to 150mA load current. A noise reduction pin is available to band-limit and lower the total integrated noise. Dual outputs provide flexibility for powering reference and regulator applications and localizing PCB routing. The outputs have excellent supply rejection and are stable with to 50F capacitors. Short circuit and thermal protection help maintain stability and prevent thermal overstress. The LT6658 is offered in the MSE16 exposed pad package.
