Analog Devices Inc. LT6658 Precision Voltage References
Analog Devices Inc. LT6658 Precision Voltage References are dual-output references that leverage the performance of a low-drift, low-noise reference, and linear regulator. The LT6658 Voltage References include two high-current output buffers. Designers can configure each output for any voltage between 2.5V and 6V. The outputs track each other over-temperature and load. Typical load regulation is 0.1ppm/mA with up to 150mA of load current.
Both outputs provide 0.05% initial accuracy, 10ppm/°C temperature drift, and 1.5ppm noise over a 0.1Hz to 10Hz frequency. The outputs deliver excellent supply rejection and are stable with 1μF to 50μF capacitors over a wide operating range. Analog Devices Inc. LT6658 is ideal for driving the reference input for high-resolution ADCs or DACs using one output while supplying power to other devices using the second output.
