STAC9711T Datasheet EXAMPLE MN5212: Return to the ideal analog input/digitaJ output transfer function of the MN5212 sketched below. Notice that the digital output data changes from 1111 1111 1111 t0 1111 1111 1110 when the input voltage increases from -10.OOOV to -9.9951V. It changes from 1111 1111 1110 back t0 1111 1111 1111 as the input voltage is decreased from some more positive voltage to -9.9951V This voltage, -9.9951V, is the negative full scale LSB transition voltage. It is the voltage at which the LSB changes from a "1" to a "0" or vice versa while all other bits remain'1: The 1000 0000 0000 t0 0111 1111 1111 transition (called the "major transition" because all the bits change) ideally occurs at the zero volt STAC9711T Price a. TA = 250C unless otherwise noted.d. b. For DESIGN AID ONLY, not subject to production testing. c. Pulse test: PW < 80 ys duty cycle il%. d. This parameter not registered with JEDEC. e. Switching time is essentially independent ofoperating temperature INB (Pin 5): Secondary Ideal Diode Anode and Positive Power Supply. Bypass INB with a ceramic capacitor of at least l uF.lQ snub resistors in series with a capacitor and higher valued capacitances are recommended when large inductances are in series with this input. This pin can be grounded when not used. |
