Notes:

1. Input and output signal voltage referenced to supply common.

2. Output is short circuit protected to common. DO NOT CONNECT TO ±Vs.

3. Adjustable to zero.

4. Units operate with or with out offset pin connected.

5. How to Specify Corner Frequency:

Corner frequencies are specified by attaching a three digit frequency

designator to the basic model number. Corner frequencies can range from

1.00 Hz to 100 kHz.
