GENERAL DESCRIPTION
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 program-
mable 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
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 program-
mable 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.
