Overview
The ISL21090BFB875Z-TK is a precision voltage reference IC from Renesas Electronics Corporation. It provides a fixed output voltage of 7.5V with an initial accuracy of ±0.035%. The device features an ultra-low noise profile and operates over a wide input voltage range up to 36V. It supports a maximum shunt current of 20 mA and exhibits a temperature coefficient of 7 ppm/°C. The component is housed in an 8-SOIC surface-mount package and functions within a temperature range of -40°C to +125°C.
Feature Summary
- Ultra-low noise performance for high-fidelity signal integrity
- High DC accuracy ensures precise voltage regulation
- Wide input voltage range accommodates diverse supply conditions
Applications
- Precision analog-to-digital converter (ADC) references
- Digital-to-analog converter (DAC) voltage sources
- High-resolution measurement instrumentation systems
Procurement Notes
Verify the specific suffix 'TK' indicates tape-and-reel packaging when ordering. Confirm the 7.5V output variant matches system requirements, as the ISL21090 series offers multiple fixed voltage options. Ensure compatibility with 8-SOIC footprint constraints during PCB layout. Check RoHS compliance status for environmental regulations.
Selection Notes
Select this component for applications requiring stable reference voltages with minimal drift. The 7.5V output suits systems needing higher headroom than standard 2.5V or 5V references. Consider the low noise characteristic for sensitive audio or RF front-end circuits. Verify that the 20 mA load capability meets the downstream circuit demands.
Part Context
The ISL21090 series utilizes Renesas Advanced Bipolar technology to achieve superior stability and low noise. This family includes various fixed output voltages, such as 2.5V and 7.5V variants. The ISL21090BFB875Z-TK specifically denotes the 7.5V version in an 8-SOIC package with reel packaging.
Replacement Considerations
Direct substitutes include other ISL21090 series variants with different output voltages if the voltage level can be adjusted externally. Cross-reference with similar high-precision bipolar voltage references from other manufacturers, ensuring pinout and thermal specifications align.
