DESCRIPTION The X60008-41 FGA™ voltage references are very high precision analog voltage references fabricated in Intersil’s proprietary Floating Gate Analog technology, which achieves superior levels of performance when compared to conventional band gap, buried zener, or XFET™ technologies. FGA™ voltage references feature very high initial accuracy, very low temperature coefficient, excellent long term stability, low noise and excellent line and load regulation, at the lowest power consumption currently available. These voltage references enable advanced applications for precision industrial & portable systems operating at significantly higher accuracy and lower power levels than can be achieved with conventional technologies.

COMMENT Absolute Maximum Ratings indicate limits beyond which permanent damage to the device and impaired reliability may occur. These are stress ratings provided for information only and functional operation of the device at these or any other conditions beyond those indicated in the operational sections of this specification are not implied. For guaranteed specifications and test conditions, see Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions.

1. Over the specified temperature range. Temperature coefficient is measured by the box method whereby the change in VOUT is divided by the temperature range; in this case, -40°C to +85°C = 125°C. 2. Thermal Hysteresis is the change in VOUT created by package stress @ TA = 25°C after temperature cycling. VOUT is read initially at TA = 25°C; the X6.
