Ultra Low Noise, 5V Precision Voltage Reference
Apr 12, 2018
The ISL71010B50 is an ultra low noise, high DC
Features
accuracy precision voltage reference, with a wide input
Reference output voltage: 5.0V 0.05%
voltage range from 7.0V to 30V. The ISL71010B50 uses
Accuracy over temperature/radiation: 0.15%
the dielectrically isolated PR40 process to achieve
4.2V noise at 0.1Hz to 10Hz with an initial voltage
P-P Output voltage noise: 4.2V typical (0.1Hz to
P-P
accuracy of 0.05%.
10Hz)
The ISL71010B50 offers a 5.0V output voltage with
Supply current: 930A (typical)
10ppm/C temperature coefficient and also provides
Temperature coefficient: 10ppm/C (maximum)
excellent line and load regulation. The device is offered
in an 8 Ld SOIC package. Output current capability: 20mA
The ISL71010B50 is ideal for high-end instrumentation, Line regulation: 20ppm/V (maximum)
data acquisition, and processing applications requiring
Load regulation: 17ppm/mA (maximum)
high DC precision where low noise performance is
NiPdAu-Ag lead finish (Sn Free)
critical.

Notes:
1. Refer to TB347 for details about reel specifications.
2. These Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials and
NiPdAu-Ag plate -e4 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering
operations. Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J STD-020.
3. For Moisture Sensitivity Level (MSL), see the ISL71010B50 product information page. For more information about MSL, refer to
TB363.
