Analog Devices Inc. EVAL-LT3097-AZ Evaluation Board features a dual 500mA regulator with positive and negative channels. The Analog Devices Inc. EVAL-LT3097-AZ has an input voltage range of 3.8V to 20V and -3.8V to -20V, respectively. Not only does it provide ultra-low noise and ultra-high power supply rejection ratio (PSRR), but each channel also features programmable power good functionality and a programmable current limit. While current monitoring is possible for the positive channel, the negative channel enable function is bidirectional and can be controlled with either a positive or negative voltage.
