MAX6079 Evaluation Kit
Evaluates: MAX6079
General Description
The MAX6079 evaluation kit (EV kit) provides a
proven design to evaluate the MAX6079 low-noise
precision ceramic voltage reference. The output voltage
is set at 2.5V.
The EV kit comes installed with a MAX6079ALA25+ in
8-pin ceramic Leadless Chip Carrier (LCC) package.

The EV kit is fully assembled and tested. Follow the steps
below to verify board operation:
Set the DC power supply to +5V. Connect the positive
terminal to the IN test point and the negative terminal
to GNDF test point.
Connect the voltmeter between OUTF and GNDF
test point.
Turn on the DC power supply.
Verify that the voltmeter displays 2.5V.

General Description of Hardware
Precision Current Source
The MAX6079 EV kit demonstrates the MAX6079, a very
low noise and low-drift voltage reference in a small 8-pin
LCC package. The EV kit requires a +2.8V to +5.5V input
supply voltage at the IN pin for normal operation.
EN
To use the EV kit as a precision current source, remove
the resistor at R3, install a 0Ω resistor at location R4, and
connect the X test point to GNDF. Install an appropriate
resistor at location R5 to determine the current by using
the following equation.

Drive the EN pin high to enable the MAX6079. Drive the
EN pin low to disable the device.
