ADI’s AD5560 is a 1.2 A programmable power supply with integrated 16-bit level setting DAC. This device includes the required DAC levels to set the programmable inputs for the drive amplifier, as well as clamping and comparator circuitry. Offset and gain correction is included on-chip for DAC functions. Five internal programmable measure current ranges fixed ranges and two external customer-selectable ranges (EXTFORCE1 and EXTFORCE2) that can supply currents up to ±1.2 A and ±500 mA, respectively, are available.
Headroom and the maximum power dissipation limit the voltage range possible at this high current level. Paralleling or ganging multiple device power supply (DPS) devices can achieve current ranges of more than ±1.2 A or at high current and high voltage combinations. Open-drain alarm outputs are provided in the event of overcurrent, overtemperature, or Kelvin alarm on either the SENSE or DUTGND line. A simple 3-wire serial interface compatible with SPI, QSPI™, MICROWIRE™, and DSP interface standards running at clock speeds of up to 50 MHz control the DPS functions. The AD5560 is ideal for automatic test equipment and power supplies.
