Power dissipation
*For DIP-16 package:
Assume VP = 6 V and RL = 8Ω
The maximum sine wave dissipation is 2 × 0.9 W = 1.8 W.
The Rthj-a of the package is 50 K/W therefore Tamb(max) = 150 - (50 × 1.8) = 60℃.
*For SOP-16 package:
Assume VP = 6 V and RL = 16Ω.
The maximum sine wave dissipation is 2 × 0.46 W = 0.92 W.
The Rthj-a of the package is 95 K/W therefore Tamb(max) = 150 - (95 × 0.92) = 62.6℃.

Notes:
1. With a load connected to the outputs the quiescent current will increase, the maximum value of this increase
being equal to the DC output offset voltage divided by RL.
2. The noise output voltage (RMS value) at fi = 500 kHz is measured with RS = 0Ω and bandwidth = 5 kHz.
3. 20 Hz to 300 kHz (typical).
4. The ripple rejection is measured with RS = 0Ω and fi = 100 Hz to 10 kHz. The ripple voltage of 200 mV (RMS
value) is applied to the positive supply rail.
5. The channel unbalance is measured with VDC1 = VDC2.
6. The channel unbalance at G1 = 0 dB is measured with VDC1 = VDC2.
7. The noise output voltage (RMS value) is measured with Rs = 5 kΩ unweighted.
