3.1.1
EVM Power Supply Input – J3
TMP116EVM utilizes the +5V input power supply of the USB connector to power the EVM. The EVM does
not require an external power supply. The board is powered by the USB port and provides sw5V.It
can be powered by shorting the J3 jumper with a regulated voltage with desired voltage based on the
equation 1. The EVM power supply input can be changed to any input power supply range of the TMP116
1.9V to 5.5V; however, note MSP430 can only support power supply range 2.3V to 3.6V with recommends
V_OH and V_OL conditions per
datasheet specifications.
The resistor adjust R_ADJ can be calculated as given by the
where V_REF=1.23V and desired
voltage of V_OUT.

Interface Connector – J1
J1 is the USB connector, and used to connect the PC. The interface is used to access the device’s
registers and read the conversion data from the TMP116 via I2C communication protocol.
