EVAL-ADP1655

ADP1655 Evaluation Board

Product Details

The evaluation system is composed of a motherboard and a daughterboard. The motherboard provides the I2C® signals from the computer USB port and generates the I/O voltages and digital high and low signals for the daughterboard. For temperature measurement, the daughterboard can either be plugged directly into the motherboard or connected to the motherboard via the ribbon cable provided with the evaluation kit.

The motherboard features a 3.3 V regulator and two adjustable regulators, one for VDDIO and one for ADP1655 supply voltage (VIC). The daughterboard contains numerous jumpers and test points for easy evaluation of the board.
