NOTES
1. THE EXPOSED PAD IS INTERNALLY ELECTRICALLY CONNECTED TO AVSS. FOR ENHANCED THERMAL, ELECTRICAL,
GUARDIN0/DUTGND0
GUARDIN2/DUTGND2
AND BOARD LEVEL PERFORMANCE, THE EXPOSED PADDLE ON THE BOTTOM OF THE PACKAGE SHOULD BE SOLDERED
TO A CORRESPONDING THERMAL LAND PADDLE ON THE PCB.

Description
Positive Analog Supply Voltage.
Compensation Capacitor Input for Channel 0. See the Compensation Capacitors section.
Sense Input (High Sense) for High Current Range (Channel 0).
Sense Input (Low Sense) for High Current Range (Channel 0).
Guard Output Drive for Channel 0.
DUT Voltage Sense Input (High Sense) for Channel 0.
Analog Ground. These pins are the reference points for the analog supplies and the measure circuitry.
DUT Voltage Sense Input (High Sense) for Channel 2.
The exposed pad is internally electrically connected to AVSS. For enhanced thermal, electrical, and board level
performance, the exposed paddle on the bottom of the package should be soldered to a corresponding
thermal land paddle on the PCB.
External Capacitor for Channel 0. 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 Internal Current Ranges (Channel 0).
Guard Amplifier Input for Channel 0/DUTGND Input for Channel 0. This dual function pin is configured via the
serial interface. The default function at power-on is GUARDIN0. If this pin is configured as a DUTGND input for
the channel, the input to the guard amplifier is internally connected to MEASVH0. For more information, see
the Device Under Test Ground (DUTGND) section and the Guard Amplifier section.
