Addition of filter capacitor will increase turn on time. Please see the Application section on power cycling. All min and max specifications are guaranteed. Typical specifications are not tested or guaranteed. Specifications subject to change without notice. (TA = TMIN to TMAX, TA = +25 C for J Grade only, VDD = +5 V, RSET = 125 k , Acceleration = 0 g, unless otherwise noted) REV. B –2– |
