VEE (—3V)
VEEA (—3V)
Note: VEE = —3.0V for 5.0V applications.
VEE = —1.3V for 3.3V applications.
Low voltage parts have L designators.
The V designator is for 5.0V applications,
i.e., SY87700L = 3.3V, SY87700V = 5.0V.
Note:
C3, C4 are optional
C1 = C2 = 0.47µF
R1 = 820Ω
R2 = 1.2kΩ
R3 through R10 = 5kΩ
R12 = 12kΩ
R13 = 130Ω
