ELECTRICAL CHARACTERISTICS
The
●
denotes specifications which apply over the full operating temperature range, otherwise specifications are TA = 25°C.
V
S
= Single 4.75V, EN pin to logic “low,” Gain = 1, R
FIL
= R11 = R21 = R31 = R12 = R22 = R32, specifications apply to both the high
speed (HS) and low power (LP) modes unless otherwise noted.
