ISL60002DIB812

Overview

The ISL60002DIB812 is a precision voltage reference IC utilizing Intersil's proprietary Floating Gate Analog (FGA) technology. It provides a fixed output voltage of 1.25V with an absolute initial accuracy of ±5.0mV and a temperature coefficient of 20ppm/°C. The device operates within a supply voltage range of 2.7V to 5.5V, consuming an ultra-low typical supply current of 400nA. It features 7mA source and sink current capability, long-term stability of 10ppm/√1,000Hrs, and ESD protection rated at 5kV (Human Body Model). Packaged in an 8-lead SOIC format, it functions across an industrial temperature range of -40°C to +85°C.

Procurement Notes

Verify the specific suffix 'B8' corresponds to the 8-lead SOIC package and 'D' indicates the ±5.0mV accuracy grade as defined in the official ordering information. Confirm that the manufacturer documentation explicitly lists this exact part number variant before procurement. Ensure compatibility with the specified 2.7V to 5.5V input range and -40°C to +85°C operating temperature for your target application environment.

Selection Notes

Select this component when designing systems requiring high precision with minimal power drain, such as battery-operated data acquisition circuits. The 1.25V output and ±5.0mV accuracy make it suitable for applications where moderate precision is acceptable but ultra-low quiescent current is critical. Consider the 7mA drive capability if driving moderate loads directly without external buffering.

Part Context

This device belongs to the ISL60002 family of FGA™ voltage references manufactured by Renesas Electronics Corporation (formerly Intersil). The family includes variants with different output voltages (1.25V, 2.50V), accuracy grades (±1.0mV, ±2.5mV, ±5.0mV), and packages (SOT23-3, SOIC-8). The ISL60002DIB812 specifically denotes the 1.25V output, ±5.0mV accuracy, and 8-lead SOIC packaging configuration.

Replacement Considerations

Compatible substitutes within the same family include ISL60002BIH312, ISL60002CIH312, ISL60002DIH312, ISL60002BIB825, ISL60002CIB825, and ISL60002DIB825. These parts share identical electrical characteristics and pinouts but differ in output voltage or accuracy grade.
