Notes:

1. Permanent device damage may occur if Absolute Maximum Ratings are exceeded. This is a stress rating only and functional operation is not implied

at conditions other than those detailed in the operational sections of this data sheet. Exposure to Absolute Maximum Rating conditions for extended

periods may affect device reliability.

2. The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.

3. Thermal performance assumes the use of 4-layer PCB. Exposed pad must be soldered (or equivalent) to the device's most negative potential on the

PCB.

4. Excludes current of CML output stage. See “Detailed Description.”

5. Total device current with no output load.

6. Output levels are based on a 50Ω to VCC load impedance. If the load impedance is different, the output level will be changed. Amplifier is in limiting

mode.
