Note 1: VIN 1 pin: VSP

Note 2: VIN 2 pins:

HUP, HVP, HWP, HUM, HVM, HWM CW/CCW, RES, Idc, FGC, Gin, TR, OSC/R, OSC/C, and Vdc

Note 3: U, V, W, X, Y, and Z

Note 4: Gout, PH, LPF/LA, and UL

Note 5: FG

Note 6: Since the Vrefout pin delivers a maximum output current of 30 mA, care should be exercised to the output

impedance.

Note 7: When mounted on a universal board (50 mm × 50 mm × 1.6 mm, Cu 40 %)

Note 8: The operating temperature range is determined by the PD - Ta characteristics.
