DESCRIPTION
No internal connection
For internal use. Do not connect
Feedback resistor RFB, positive terminal
+RFB positive sense pin connects to the resistor RFB+ terminal to form the RFB+ Kelvin connection.
-RFB negative sense pin connects to the resistor RFB- terminal to form the RFB- Kelvin connection.
Feedback resistor RFB, negative terminal
Ground pin is capacitively coupled to the internal ESD circuit and should be connected to power supply
common or signal GND. Also connected to the lid.
Positive supply for input stage and feedback amplifier
Positive supply for output stage
Positive output feedback
Positive output
Output common-mode reference input
Negative supply for output stage
Negative supply for input stage and feedback amplifier
Input resistor RIN, negative terminal
-RIN negative sense pin connects to the resistor RIN- terminal to form the RIN- Kelvin connection.
+RIN positive sense pin connects to the resistor RIN+ terminal to form the RIN+ Kelvin connection.
Input resistor RIN, positive terminal
Negative input
Positive input
Package lid is internally connected to GND (Pin 8).
