LT6658AHMSE-3.3#PBF

LT6658AHMSE-3.3#PBF is a precision dual output, high current, low noise, voltage reference. This precision dual output reference combines the performance of a precision voltage reference and a linear regulator that we call the Refulator™. Both outputs are ideal for driving the reference inputs of high resolution ADCs and DACs, even with heavy loading, while simultaneously powering microcontrollers and other circuitry. Both outputs have same precision specifications and track each other over temperature and load. Each output can be configured with external resistors to give an output voltage up to 6V. Using Kelvin connections, the LT6658 typically has 0.1ppm/mA load regulation with up to 150mA load current. A noise reduction pin is available to band-limit and lower total integrated noise. Applications include microcontroller or FPGA with ADC/DAC applications, data acquisition systems, automotive control and monitoring, precision low noise regulators, instrumentation and process control.
