Note:
1.
For asymmetrical power supplies (with the load short-circuited), the maximum unloaded supply voltage is
limited to V
P
= 28 V and the maximum unloaded supply voltage is limited to 32 V(with the load
short-circuited) with an internal supply resistance of R
S
≥4Ω.
The circuit is short-circuit-proof up to
V
P
= ±21 V for symmetrical power supplies.
2. Absolute maximum ratings are those values beyond which the device could be permanently damaged.
Absolute maximum ratings are stress ratings only and functional device operation is not implied.

3 dB output power
3. The noise output voltage (RMS value) is measured at R
S

4. The ripple rejection is measured at R
S
= 0 and f = 100 Hz to 20 kHz. The ripple voltage (200 mV) is applied
in phase to the positive and the negative supply rails. With asymmetrical power supplies, the ripple rejection
is measured at f = 1 kHz

7. At pin 2 it is a resistor devider of typical 4kΩ and 5kΩ to the positive supply rail. And at the connection of the
4kΩ and 5kΩ resistor a zener diode of typical 6.6 V is also connected to the positive supply rail. The zener’s
spread voltage is 6.1 to 7.1 V.
