X60008AIS8-50

Overview

The X60008AIS8-50 is a precision low-power voltage reference utilizing Intersil’s proprietary Floating Gate Analog (FGA) technology. It provides a nominal output voltage of 5.000V with an absolute initial accuracy of ±0.5mV and a maximum temperature coefficient of 1ppm/°C over the -40°C to +85°C industrial range. The device features ultra-low supply current, typically 500nA and maximum 800nA, enabling extended battery life in power-sensitive applications. It supports continuous sourcing and sinking of up to 10mA load current, with a guaranteed short-circuit current of 80mA. Line regulation is specified at 20ppm/V, and long-term stability is rated at 10ppm per 1,000 hours.

Procurement Notes

Verify component authenticity by checking the manufacturer marking code against official documentation. Confirm the package type matches the standard SOIC-8 specification. Ensure the operating environment remains within the specified -40°C to +85°C temperature range. Validate that input voltage stays between 5.1V and 9.0V to maintain guaranteed performance parameters. Check for RoHS compliance status if lead-free material sets are required for assembly processes.

Selection Notes

Select this component when design requirements demand extremely low quiescent current alongside high precision. The FGA technology offers superior thermal hysteresis performance compared to traditional bandgap references. Consider the 7ms typical turn-on time when designing system startup sequences. Evaluate noise reduction networks if operation occurs in bandwidths exceeding 10Hz. Ensure board mounting locations minimize mechanical stress on the die to preserve accuracy specifications.
