Evaluates: MAX6226 MAX6226 Evaluation Kit General Description Quick Start The MAX6226 evaluation kit (EV kit) provides a proven Required Equipment design to evaluate the MAX6226 low-noise precision MAX6226 EV kit ceramic voltage reference. The output voltage is set at +5V DC power supply 2.5V. Voltmeter The EV kit comes installed with a MAX6226ALA25+ in 8-pin ceramic Leadless Chip Carrier (LCC) package. To Procedure evaluate other output voltage options, replace the U1 IC The EV kit is fully assembled and tested. Follow the steps preinstalled with the desired part. below to verify board operation: 1) Set the DC power supply to +5V. Connect the positive Features terminal to the IN test point and the negative terminal Configurable for Precision Current Source to GND test point. Proven PCB Layout 2) Connect the voltmeter between OUTF and GND Fully Assembled and Tested test point. Ordering Information appears at end of data sheet. 3) Turn on the DC power supply. 4) Verify that the voltmeter displays 2.5V. MAX6226 EV Kit Photo 319-100293 Rev 1 11/21 2021 Analog Devices, Inc.

Install an appropriate LCC package. The EV kit requires a +2.7V to +12.6V resistor at location R5 to determine the current by using input supply voltage at the IN pin for normal operation. the following equation.
