ISL71010BM25EV1Z
Evaluation Board
USER’S MANUAL
1.
Overview
The ISL71010BM25EV1Z evaluation board measures the performance of the high precision 2.5V
voltage reference. The reference has a wide input voltage range from 4V to 30V and an initial accuracy of ±0.05%. The
voltage noise of 1.9µV
P-P
in the 0.1Hz to 10Hz range and maximum output voltage temperature coefficient of 10ppm/°C
makes the ISL71010B25 ideal for high end applications.
The evaluation board includes voltage input test points (VIN and GND) for a power supply input, as well as a pair of
test points for the output (VOUT and GND). The resistor location designated as R2 and the capacitor location
designated as C3 allow VOUT output load testing. The R2 resistor location accepts surface mount or through-hole
style resistors and C3 comes populated with a 0.1µF load capacitor. Additionally, an R-C damper network can be
connected to VOUT by installing a jumper at J1.
