Note 1

Pins 3 4 5 10 11 12 at 25 C Derate at 15 CW above 25 C case

Note 2

The amplifier should be in high gain for full swing on higher supplies due to input voltage limitations

Note 3

If load and bypass capacitor are returned to VS (Figure 2) rather than ground (Figure 1) PSRR is typically 30 dB
