Overview
The ISL21009DFB841Z-TK is a high voltage input precision, low noise FGA™ voltage reference manufactured by Intersil. It provides an output voltage of 4.096V with an initial accuracy of ±2.0mV. The device operates within an input voltage range of 3.5V to 16.5V and features an output voltage noise of 4.5μVP-P (0.1Hz to 10Hz). Supply current is 180μA maximum, with a temperature coefficient of 10ppm/°C. Output current capability reaches up to ±7.0mA. It functions in temperatures from -40°C to +125°C and is housed in an 8 Ld SOIC package.
Feature Summary
- Delivers high precision voltage referencing with low noise characteristics suitable for sensitive analog circuits.
- Supports wide input voltage ranges allowing flexibility in power supply design.
- Provides stable output performance across extended industrial temperature ranges.
Applications
- High Resolution A/Ds and D/As
- Digital Meters
- Industrial Instrumentation Equipment
Procurement Notes
Verify the specific suffix TK against official Renesas documentation to confirm tape-and-reel packaging specifications. Ensure the part number matches the exact voltage and accuracy grade required for your design. Cross-reference the manufacturer date code and RoHS compliance status with the latest datasheet revisions before procurement.
Selection Notes
Select this component when a 4.096V reference with ±2.0mV initial accuracy is required. Consider the 10ppm/°C temperature coefficient for thermal stability needs. The 8 Ld SOIC package suits standard surface mount assembly processes. Evaluate the 180μA supply current against system power budget constraints.
Part Context
This part belongs to the ISL21009 series of FGA™ voltage references. The series includes variants with different output voltages such as 1.250V, 2.500V, and 5.000V. These devices are designed for applications requiring high precision and low noise in signal chain components.
Replacement Considerations
Check for direct substitutes like ISL21009DFB841Z or other ISL21009 variants with matching 4.096V output and ±2.0mV accuracy. Verify pinout compatibility and package dimensions before substitution.
