The AD5560 is a high performance, highly integrated device power supply consisting of programmable force voltages and measure ranges. This part 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. A number of programmable measure current ranges are available: five internal fixed ranges and two external customer-selectable ranges (EXTFORCE1 and EXTFORCE2) that can supply currents up to ±1.2 A and ±500 mA, respectively. The voltage range possible at this high current level is limited by headroom and the maximum power dissipation. Current ranges in excess of ±1.2 A or at high current and high voltage combinations can be achieved by paralleling or ganging multiple DPS devices. Open-drain alarm outputs are provided in the event of overcurrent, overtemperature, or Kelvin alarm on either the SENSE or DUTGND line.

The DPS functions are controlled via a simple 3-wire serial interface compatible with SPI, QSPI^™, MICROWIRE^™, and DSP interface standards running at clock speeds of up to 50 MHz.
