Detailed Description for ISL21007DFB825Z
Product Overview
The Intersil ISL21007DFB825Z is a fixed-output series voltage reference intended for circuits that require a stable 2.5V reference. It accepts an input voltage from 2.7V to 5.5V, supplies a 5 mA output current, and maintains a specified tolerance of ±0.16%. The device is housed in a surface-mount 8-SOIC package with a 0.154-inch (3.90 mm) body width and is specified for operation from -40°C to 125°C (TA). Its 10ppm/°C temperature coefficient and 4.5µVp-p noise over 0.1Hz to 10Hz support precision analog and data-conversion front ends where reference stability and low disturbance are important.
Key Features
- Fixed 2.5V series voltage reference output
- Tolerance of ±0.16%
- Output current of 5 mA
- Input voltage range of 2.7V to 5.5V
- Temperature coefficient of 10ppm/°C
- Noise of 4.5µVp-p over 0.1Hz to 10Hz
- Supply current of 150µA
- Surface-mount 8-SOIC package
- Operating temperature range of -40°C to 125°C (TA)
Applications
- Precision analog-to-digital converter reference input
- DAC reference input in fixed 2.5V scaling applications
- Sensor signal conditioning circuits requiring a stable reference
- Measurement front ends where low-frequency noise and tolerance affect accuracy
Design & Procurement Notes
Designers should verify that the available supply remains within 2.7V to 5.5V and that the connected reference load is compatible with the 5 mA output current. The 150µA supply current should be included in the system power budget. The ±0.16% tolerance and 10ppm/°C coefficient should be considered when defining calibration limits and drift budgets. The 4.5µVp-p noise over 0.1Hz to 10Hz is relevant to sensitive measurement chains. The 8-SOIC surface-mount package requires a matching PCB footprint.
