Pin 7 Voltage to Pin 3
● 1.0 1.3 1.5 V
Pin 6 Voltage to Pin 3 ● –1.0 –1.3 –1.5 V
The ● denotes specifications which apply over the full operating
temperature range.
Note 1: External power devices may require heat sinking.
Note 2: Commercial grade parts are designed to operate over the
temperature range of –40°C to 85°C but are neither tested nor guaranteed
beyond 0°C to 70°C. Industrial grade parts specified and tested over
–40°C and 85°C are available on special request, consult factory.

Note 5: The input resistance is typically 15MΩ when the loop is closed.
When the loop is open (current limit) the input resistance drops to 200Ω
referred to Pin 3.
Note 6: Maximum T
J
can be exceeded with 50mA operating current and
simultaneous 10V and –10V (20V total).
Note 7: Apply ±200mV to Pin 2 and measure current change in Pin 1
and 4. Pin 3 is grounded.
Note 8:
Note 9: For Linear Operation, Pin 1 must not be less than 2V or more than
10V from Pin 3. Similarly, Pin 4 must not be less than 2V or more than
10V from Pin 3.
Pin 1 = 2V, Pin 4 = –2V, Operating current 15mA and R
