MikroElektronika Boost-INV 2 Click Board

Boost-INV 2 click is a very useful DC/DC voltage converter device, as can output both positive and negative voltage, boosted up to 15V and inverted to -15V, from a single fixed voltage input. The input voltage can vary between 2.7V to 5.5V, making the Boost-INV 2 click an ideal solution for powering devices with complex, split-rail power supply demands, using only a common battery. The Click board™ is equipped with two additional D/A converters, which make it possible to digitally set the output voltage, via the SPI.12-Bit Resolution ±0.2 LSB DNL (typ) ±2 LSB INL (typ) Single or Dual Channel Rail-to-Rail Output SPI™ Interface with 20 MHz Clock Support Simultaneous Latching of the Dual DACs w/LDAC Fast Settling Time of 4.5 μs Selectable Unity or 2x Gain Output 450 kHz Multiplier Mode External VREF Input 2.7V to 5.5V Single-Supply Operation Extended Temperature Range: -40°C to +125°C Applications Set Point or Offset Trimming Sensor Calibration Digitally-Controlled Multiplier/Divider Portable Instrumentation (Battery-Powered) Motor Feedback Loop Control
