‡ -20dBm=63mVPP into 50Ω
Notes: 1. Includes input offset voltage contribution
†. VSENSE is defined as the differential voltage between VSENSE+ and VSENSE-.
VSENSE = VSENSE+ - VSENSE-
Absolute Maximum Ratings
| Description | Rating | Unit | |
|---|---|---|---|
| Voltage on any pin (relative to IOUT) | -0.6 to 20 | V | |
| Continous output current, IOUT | 25 | mA | |
| Continuous sense voltage, VSENSE | † | -0.5 to +5 | V |
| Operating temperature, TA | -40 to 85 | °C | |
| Storage temperature | -55 to 125 | °C | |
| Package power | SOT23 | 450 | mW |
| dissipation @ TA = 25°C (Derate to zero @ 125°C) | SM8 | 2 | W |
Operation above the absolute maximum rating may cause device failure. Operation at the absolute maximum ratings for extended periods may reduce device reliability.
