1.2个可编程设备的电源集成16位级别设置AD5560数据表

　　TheAD5560 is a high performance， highly integrated device power supply consisting of programmable force voltages and measure ranges. This part includes the requiredDAClevels 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） thatcansupply currents up to ±1.2 A and ±500 mA， respectively. The voltage range possible at this high current level is limited by headroom and themaximum power dissipation. Current ranges in excess of ±1.2 A or at high current and high voltage combinations can beachieved by paralleling or ganging multiple DPS devices. Open-drain alarmoutputs are provided in the event of overcurrent， overtemperature， or Kelvin alarm on either the SENSE or DUTGND line. The DPS functions are controlledvia asimple 3-wire serial interface compatible with SPI， QSPI™， MICROWIRE™， andDSPinterface standards running at clock speeds of up to 50 MHz.
