PIN FUNCTIONS
TYPICAL PERFORMANCE CHARACTERISTICS
Step Response Falling Edge
PSRR vs Frequency
OUT (Pin 1): Current Output. OUT will source or sink a
current that is proportional to the sense voltage into an
external resistor. A voltage reference is required to provide
the proper positive offset voltage so that the output can
swing both positive and negative.
V– (Pin 4): Negative Supply (or Ground for Single-Supply
Operation).
+INB/VS (Pin 5): The positive input of the internal sense
amplier B. It also works as the positive supply input.
Supply current is drawn through this pin.
–INB (Pin 6): The negative input of the internal sense
amplier B. The internal sense amplier will drive –INB
to the same potential as +INB when VSENSE is negative.
A resistor (RIN) tied from one end of RSENSE to –INB sets
the output current IOUT = VSENSE/RIN. VSENSE is the voltage
developed across the external RSENSE (Figure 1).
–INA (Pin 7): The negative input of the internal sense
amplier A. The internal sense amplier will drive –INA
to the same potential as +INA when VSENSE is positive. A
resistor (RIN) tied from one end of RSENSE to –INA sets
the output current IOUT = VSENSE/RIN.
+INA (Pin 8): The positive input of the internal sense
amplier A.
