The q denotes the specifications which apply over the full operating
temperature range, otherwise specifications and typical values are at TA = 25°C. VS = single 5V, EN pin to logic “low,” RL = 400,
connected to midsupply, RFIL = R11 = R21 = R31 = R12 = R22 = R32, unless otherwise noted (see Block Diagram).

ELECTRICAL CHARACTERISTICS
Specifications are for the output (OUTA or OUTB) of a
single 2nd order section (A or B) with respect to VGND = VGNDA = VGNDB,
gain = –1, RFIL = R11 = R21 = R31 = R12 = R22 = R32, (see Block Diagram). The q denotes the specifications which apply over the
full operating temperature range, otherwise specifications and typical values are at TA = 25°C. VS = single 5V, EN pin to logic “low,”
RL = 400, unless otherwise noted.
