|---|---|
| Output power | 14 W (d = 0.5 %) at 14 V/4 Ω |
| Output peak current | 3.5 A (internally limited) |
| Power dissipation (Tcase = 90 °C) | 20 W |
| Thermal resistance (junction‑case) | 3 °C/W max |
| Quiescent drain current | 40–60 mA |
| Input offset voltage | +2 to +20 mV |
| Open‑loop voltage gain | 90 dB |
| Input resistance (pin 1) | 0.5–5 MΩ |
The device can be operated with a supply voltage up to +18 V.
It includes an original short‑circuit protection circuit that limits the current of the output transistors.
The thermal shut‑down circuit reduces power dissipation to keep the junction temperature below 150 °C.
