Evaluates: MAX6079 MAX6079 Evaluation Kit General Description Quick Start The MAX6079 evaluation kit (EV kit) provides a Required Equipment proven design to evaluate the MAX6079 low-noise MAX6079 EV kit precision ceramic voltage reference. The output voltage +5V DC power supply is set at 2.5V. Voltmeter The EV kit comes installed with a MAX6079ALA25+ in 8-pin ceramic Leadless Chip Carrier (LCC) package. Procedure The EV kit is fully assembled and tested. Follow the steps Features below to verify board operation: Configurable for Precision Current Source 1) Set the DC power supply to +5V. Connect the positive Proven PCB Layout terminal to the IN test point and the negative terminal Fully Assembled and Tested to GNDF test point. 2) Connect the voltmeter between OUTF and GNDF Ordering Information appears at end of data sheet. test point. 3) Turn on the DC power supply. 4) Verify that the voltmeter displays 2.5V.

Install an appropriate LCC package. The EV kit requires a +2.8V to +5.5V input resistor at location R5 to determine the current by using supply voltage at the IN pin for normal operation. the following equation. EN V Drive the EN pin high to enable the MAX6079. Drive the OUT I = SOURCE EN pin low to disable the device. R5 Ordering Information PART TYPE MAX6079EVKIT EV Kit Denotes RoHS compliant.
