Each output is trimmed to ±0.1% initial accuracy and rated for 20 mA continuous current — enough to drive an ADC reference input and a sensor bridge simultaneously without a buffer. The 1.8V fixed output is the primary reference; the second output is adjustable up to 6V via an external divider, giving flexibility for mixed-voltage analog front-ends in a single package. For a 16-bit ADC with a 1.8V reference, 1 ppm corresponds to about 1.8 µV p-p at the reference input — well below the 1 LSB noise floor of most SAR converters, meaning the reference doesn't limit the converter's effective resolution. The temperature coefficient is 20 ppm/°C. ## Package and board integration — the exposed pad matters No reel or tape options are listed — plan for manual placement or a tube-fed pick-and-place if volume demands it. ## Active production, RoHS3 compliant — no lifecycle risk It is fully RoHS3 compliant (no lead, no exemptions), so it passes EU material restrictions without paperwork exceptions.","metaTitle":"LT6658BIMSE-1.8#PBF Dual Voltage Reference, ±0.1%, 20 mA","metaDescription":"LT6658BIMSE-1.8#PBF dual voltage reference from Analog Devices. ±0.1% tolerance, 20 mA output, 1.8V fixed.
