    Abstract: The MAX77640/MAX77641 provide highly integrated power supply solutio for low-power applicatio where size and efficiency are critical. The MAX77640/MAX77641 device datasheet provides the complete hardware and electrical description for these devices. This Programmer’s Guide focuses on the register map for the devices and provides general advice for programme. Changing Regulator Output Voltages The regulator output voltages are programmable. When a regulator is off, the output voltage may be directly programmed. However, when the regulator is on and the output voltage needs to be increased or decrease program a voltage ramp from the existing voltage to the new desired voltage. Programming a ramp is recommended for voltage increases to minimize inrush current. Programming a ramp is recommended on voltage decreases to minimize regulator undehoot when it reaches its target voltage.

    A team of researche have created a new Atomic Force Microscope with the help of Analog Devices electronics. In particular, they measure the tiny currents produced by the piezoelectric effect with a traimpedance amplifier, which coists into a current-to-voltage converter. The work entitles “Piezo-generated charge mapping revealed through direct piezoelectric force microscopy” published in the prestigious scientific journal Nature Communicatio.
