ISL71010B25

Ultra Low Noise, 2.5V Precision Voltage Reference

FN8960

Rev.1.00

Apr 12, 2018

The ISL71010B25 is an ultra low noise, high DC

accuracy precision voltage reference with a wide input

voltage range from 4V to 30V. The ISL71010B25 uses

the dielectrically isolated PR40 process to achieve

Features

• Reference output voltage: 2.5V ±0.05%

• Accuracy over temperature/radiation: ±0.15%

1.9µV noise at 0.1Hz to 10Hz with an initial voltage

accuracy of ±0.05%.

• Output voltage noise: 1.9µV typical (0.1Hz to

10Hz)

P-P

The ISL71010B25 offers a 2.5V output voltage with

10ppm/°C temperature coefficient and also provides

excellent line and load regulation. The device is offered

in an 8 Ld SOIC package.

• Supply current: 930µA (typical)

• Temperature coefficient: 10ppm/°C (max)

• Output current capability: 20mA

• Line regulation: 18ppm/V (max)

• Load regulation: 17ppm/mA (max)

• NiPdAu-Ag lead finish (Sn free)

• Dielectrically isolated PR40 process

• Operating temperature range: -55°C to +125°C

• Passes NASA Low Outgassing Specifications

• Characterized radiation level:

The ISL71010B25 is ideal for high-end instrumentation,

data acquisition, and processing applications requiring

high DC precision where low noise performance is

critical.

Applications

• Low Earth Orbit (LEO)

• High altitude avionics

• Precision instruments

• Low dose rate (10mrad(Si): 30krad(Si)

• Single event burnout LET: 43MeV•cm2/mg

• Data acquisition systems for space applications

• Strain and pressure gauges for space applications

• Active sources for sensors
