Description
Interface Select Pin. Logic low selects SPI-compatible interface mode; logic high selects LVDS interface mode.
This pin has a pull-down current source (~350 μA). In LVDS interface mode, the CPOHx and CPOLx pins default
to differential interface pins.
Positive Analog Supply Voltage.
DUT Voltage Sense Input (Low Sense). By default, this input is shared among all four PMU channels. If a DUTGND
input is required for each channel, the user can configure the GUARDINx/DUTGNDx pins as DUTGND inputs for
each PMU channel.
Reference Input for DAC Channels. 5 V for specified performance.
Accurate Analog Reference Input Ground.
External Sense Signal Output. This pin enables the connection of the system PMU.
Analog Ground. These pins are the reference points for the analog supplies and the measure circuitry.
External Force Signal Input. This pin enables the connection of the system PMU.
Multiplexed DUT Voltage, Current Sense Output, Temperature Sensor Voltage for Channel 0. This pin is
referenced to AGND.
Multiplexed DUT Voltage, Current Sense Output, Temperature Sensor Voltage for Channel 1. This pin is
referenced to AGND.
Multiplexed DUT Voltage, Current Sense Output, Temperature Sensor Voltage for Channel 2. This pin is
referenced to AGND.
Multiplexed DUT Voltage, Current Sense Output, Temperature Sensor Voltage for Channel 3. This pin is
referenced to AGND.
Force Output for High Current Range (Channel 1). Use an external resistor at this pin for current ranges up to
±80 mA. For more information, see the Current Range Selection section.
External Capacitor for Channel 1. This pin optimizes the stability and settling time performance of the force
amplifier when in force voltage mode. See the Compensation Capacitors section.
Compensation Capacitor Input for Channel 1. See the Compensation Capacitors section.
Sense Input (High Sense) for High Current Range (Channel 1).
Sense Input (Low Sense) for High Current Range (Channel 1).
Force Output for Internal Current Ranges (Channel 1).
Guard Output Drive for Channel 1.
Guard Amplifier Input for Channel 1/DUTGND Input for Channel 1. This dual function pin is configured via the
serial interface. The default function at power-on is GUARDIN1. If this pin is configured as a DUTGND input for
the channel, the input to the guard amplifier is internally connected to MEASVH1. For more information, see
the Device Under Test Ground (DUTGND) section and the Guard Amplifier section.
DUT Voltage Sense Input (High Sense) for Channel 1.
DUT Voltage Sense Input (High Sense) for Channel 3.
Guard Amplifier Input for Channel 3/DUTGND Input for Channel 3. This dual function pin is configured via the
serial interface. The default function at power-on is GUARDIN3. If this pin is configured as a DUTGND input for
the channel, the input to the guard amplifier is internally connected to MEASVH3. For more information, see
the Device Under Test Ground (DUTGND) section and the Guard Amplifier section.
Guard Output Drive for Channel 3.
Force Output for Internal Current Ranges (Channel 3).
Sense Input (Low Sense) for High Current Range (Channel 3).
Sense Input (High Sense) for High Current Range (Channel 3).
Compensation Capacitor Input for Channel 3. See the Compensation Capacitors section.
External Capacitor for Channel 3. This pin optimizes the stability and settling time performance of the force
amplifier when in force voltage mode. See the Compensation Capacitors section.
Force Output for High Current Range (Channel 3). Use an external resistor at this pin for current ranges up to
±80 mA. For more information, see the Current Range Selection section.
Comparator Output High (Channel 3) for SPI Interface/Comparator Output Window (Channel 3) for LVDS
Interface.
Comparator Output Low (Channel 3) for SPI Interface/Comparator Output Window (Channel 2) for LVDS
Interface.
Comparator Output High (Channel 2) for SPI Interface/Comparator Output Window (Channel 1) for LVDS
Interface.
