Description
Clamp Alarm Output. Open-drain output, active low; this pin can be programmed to be either latched or
unlatched.
Kelvin Alarm Pin for SENSE and DUTGND, Open-Drain Active Low. This pin can be programmed to be either
latched or unlatched.
Temperature Alarm Flag. Open-drain output, active low; this pin can be programmed to be either latched or
unlatched.
Comparator High Output (CPOH) or Window Comparator Output (CPO).
Comparator Low Output.
Open-Drain Active Low Output. This pin indicates the status of the calibration engine for the DAC channels.
Serial Data Output. This pin is used for reading back DAC and DPS register information for diagnostic
purposes.
Digital Supply Voltage.
Digital Ground Reference Point.
Clock Input, Active Falling Edge.
Serial Data Input.
Frame Sync, Active Low.
Ramp Clock Logic Input. If the ramp function is used, a clock signal of 833 kHz maximum should be applied to
this input to drive the ramp circuitry. Tie RCLK low if it is unused.
Logic Input. This pin is used to reset all internal nodes on the device to their power-on reset value.
Clamp Enable. This input allows the user to enable or disable the clamp circuitry. This pin can be configured
as a LOAD function to allow synchronization of multiple devices. Either CLEN or HW_INH can be chosen as
LOAD input (see the system control register, Address 0x1).
Hardware Inhibit Input to Disable Force Amplifier. This pin can be configured as a LOAD function to allow
synchronization of multiple devices. Either CLEN or HW_INH can be chosen as a LOAD input (see the system
control register, Address 0x1).
Accurate Ground Reference for Applied Voltage Reference.
