Use it within the allowable dissipation range. (2) Minimize the common impedance of power supply line of 6 pin and 11 pin. (3) Inductor and capacitor of series resonance can be removed. Treat them with great care when removing them, because the terminal may catch noise component. Even if they are removed, attenuation in TRAP frequency are not expected so much. !External dimensions (Units : mm) 13.6±0.2 17 1 16 1.8±0.1 0.11 7.8±0.3 5.4±0.2 0.3Min. 32 0.8 0.36±0.1 0.15±0.1 0.1 SSOP-A32 9/9
