Description

The LT6658 is a family of precision dual output references combining 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 the 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 the total integrated noise.Separate supply pins are provided for each output, providing an option to reduce power consumption and isolate the buffer amplifiers. The outputs have excellent supply rejection and are stable with 1µF to 50µF capacitors.The LT6658 is available in a 16-lead MSOP and DFN with an exposed pad for thermal management. Short circuit and thermal protection help to prevent thermal overstress.APPLICATIONSMicrocontroller or FPGA with ADC/DAC ApplicationsData Acquisition SystemsAutomotive Control and MonitoringPrecision Low Noise RegulatorsInstrumentation and Process Control
