ELECTRICAL CHARACTERISTICS (VS = 5V) The l denotes the specifications which apply across the
specified temperature range, otherwise specifications are at TA = 25°C. For each amplifier VS = 5V, 0V; VSHDN = 2V; VCM = VOUT =
2.5V, unless otherwise noted.
ELECTRICAL CHARACTERISTICS (VS = 2.7V) The l denotes the specifications which apply across the
specified temperature range, otherwise specifications are at TA = 25°C. For each amplifier VS = 2.7V, 0V; VSHDN = 2V; VCM = VOUT =
1.35V, unless otherwise noted.
