Renesas X60008AIS8-50

Overview

X60008AIS8-50 from Intersil is a precision 5.0V floating-gate analog (FGA™) voltage reference IC with 1ppm/°C max temperature coefficient, ±0.5mV initial accuracy, and ultra-low 800nA max supply current - designed for high-resolution data acquisition systems requiring long-term stability and battery-compatible power consumption.

For engineers reviewing the X60008AIS8-50 datasheet, X60008AIS8-50 pinout, X60008AIS8-50 application, or X60008AIS8-50 equivalent, this device delivers verified low-noise (30µV_p-p, 0.1–10Hz), 10ppm thermal hysteresis, 10mA source/sink capability, and SOIC-8 packaging suitable for precision A/D converters, calibration systems, and smart sensor references.

Technical Context

The X60008AIS8-50 employs proprietary Floating Gate Analog (FGA™) technology to achieve near-zero drift without bandgap or Zener constraints, enabling programmable reference voltages with factory-trimmed charge storage on an isolated gate. Its buffered output architecture supports both sourcing and sinking up to 10mA while maintaining <20µV/mA load regulation.

It operates from 5.1V to 9.0V input, exhibits 100µV/V line regulation (or 20ppm/V), and features a 7ms typical turn-on time due to nanopower biasing. Thermal hysteresis is characterized at 10ppm over ±25°C cycling and 50ppm over full -40°C to +85°C range, confirming robustness in industrial environments.

FAQ

What is the maximum input voltage for the X60008AIS8-50?

The X60008AIS8-50 has an absolute maximum input voltage rating of +10V on VIN relative to GND. However, its recommended operating input voltage range is +5.1V to +9.0V. Operating above +9.0V may degrade long-term stability or increase supply current beyond the 800nA maximum specification. The X60008AIS8-50 is not rated for operation at 10V continuous - sustained use at that level risks accelerated aging and reduced 10ppm/1,000hrs stability compliance.

Does the X60008AIS8-50 require an external capacitor on VOUT for stability?

Yes, the X60008AIS8-50 requires at least a 0.001µF ceramic capacitor from VOUT to GND for optimal noise performance and transient response. Without it, output noise rises to ~400µV_p-p in the 10kHz–1MHz band, and load step response degrades significantly. For full-bandwidth noise reduction (<40µV_p-p, 1Hz–1MHz), the datasheet recommends the RC network: 2kΩ in series with 10µF, plus a parallel 0.01µF capacitor - all referenced to the X60008AIS8-50's dual GND pins.

Can the X60008AIS8-50 sink current, and how much?

Yes, the X60008AIS8-50 is fully bidirectional and can sink up to 10mA continuously while maintaining ≤100µV/mA load regulation. It also supports 80mA short-circuit current continuously - verified per datasheet Electrical Characteristics table. This capability enables use in precision current sinks, active shunt regulators, and bipolar reference circuits where the X60008AIS8-50 actively pulls current from downstream loads rather than just sourcing.

Is the X60008AIS8-50 RoHS compliant and lead-free?

Yes, the X60008AIS8-50 is RoHS compliant and offered in a Pb-free plus anneal configuration (ordering code X60008AIS8Z-50). It uses 100% matte tin plating and RoHS-compliant molding compounds, qualified for both SnPb and Pb-free reflow profiles per IPC/JEDEC J-STD-020. The standard X60008AIS8-50 variant is also RoHS compliant but uses a different termination finish - both meet EU Directive 2011/65/EU requirements.

How does the X60008AIS8-50 achieve 1ppm/°C temperature coefficient?

The X60008AIS8-50 achieves 1ppm/°C max temperature coefficient through Intersil's proprietary Floating Gate Analog (FGA™) process, which stores precise charge on an electrically isolated gate - eliminating reliance on silicon bandgap or Zener diode physics. This architecture avoids intrinsic temperature dependencies of junction-based references, and the 1ppm/°C value is measured using the industry-standard "box method" across -40°C to +85°C, as confirmed in the FN8139.1 datasheet.
