Note:1. All voltages are measured with respect to the ground (GND) pins, unless otherwise specified.
2. Depends on the offset voltage when a practical load is connected to the amplifier.
3. When driving 3Ω or 4Ω and operating on a 5V supply, the HTSSOP-20 package must be mounted to the
circuit board that has a minimum of 2.5 in2 of exposed, uninterrupted copper area connected to the
exposed-DAP.
