Description
The X60003 FGA™ voltage references is a very high precision analog voltage reference 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 and portable systems operating at significantly higher accuracy and lower power levels than can be achieved with conventional technologies.

- Application NotePDF 421 KB an1533 Aug 19, 2009AI-generated Summary: X-ray exposure causes a measurable negative shift in the output voltage of Intersil FGA reference devices, approximately 61µV per mrem. Voltage shift is proportional to the programmed output voltage and X-ray dose. Zinc foil effectively filters harmful low-energy X-rays, reducing voltage drift significantly. Copper and aluminum filters also reduce drift but require greater thickness. The copper leadframe and PCB copper planes provide additional shielding. Reducing X-ray exposure time, tube current, and increasing distance minimize voltage shifts. Airport carry-on X-rays also cause minor shifts.
- Application NotePDF 267 KB an1494 Jun 17, 2009AI-generated Summary: The document analyzes the effects of reflow soldering on the accuracy and hysteresis of precision voltage references from various manufacturers, including Intersil FGA references. It presents detailed measurement data before and after multiple reflow passes, showing minimal voltage shifts. The document also includes a notice outlining Renesas Electronics' liability disclaimers, product quality classifications, usage guidelines, and contact information for global sales offices.
- Application NotePDF 1.39 MB an177 Jun 13, 2005AI-generated Summary: Bandgap voltage references generate stable output voltages by combining two temperature-dependent voltages to cancel temperature drift, typically around 1.24V. They operate with low voltage (<5V), low current (<1mA), and moderate temperature drift (>20ppm/°C). Buried Zener references offer low noise and temperature drift but require higher voltage (>7V) and current (>1.5mA). Intersil Floating Gate Analog technology stores precise voltages on a floating gate, achieving very low temperature drift (1ppm/°C), high accuracy, and ultra-low current (<1µA). Key specs include absolute accuracy and temperature coefficient, with advanced methods to measure and reduce drift.
- Application NotePDF 503 KB an9675 Aug 13, 1999AI-generated Summary: Effective Number of Bits (ENOB) depends critically on precise coherence in A/D sampling, with small frequency shifts significantly impacting accuracy. Unwrapping reconstructs coherently sampled sine waves, while windowing controls spectral leakage by shaping the acquisition window. Resampling and interpolation adjust sample sets to avoid leakage in FFT analysis. Different window functions balance side lobe levels and bandwidth, affecting spectral resolution and leakage reduction.
- Application NotePDF 287 KB an9705 Feb 21, 1997AI-generated Summary: Coherent sampling requires the ratio of signal frequency to sampling frequency to be a rational number, expressed as ko/N. When this condition is not met, frequency smearing occurs across bins. Data Acquisition Systems (DAS) can mitigate this by windowing, fixing sampling frequency and tuning input frequency, or fixing input frequency and tuning sampling frequency. The latter two methods are practical for most systems. Pseudo-code illustrates the frequency response for non-integer ko values.
