(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.
(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.
