13 / 20 page  Functional Description (Continued) This zener is intended for use as a shunt voltage regulator to eliminate the need for any additional regulating compo- nents This is most desirable if the converter is to be re- motely located from the system power source Figures 4 and 5 illustrate two useful applications of this on-board ze- ner when an external transistor can be afforded An important use of the interconnecting diode between Va and VCC is shown in Figures 6 and 7 Here this diode is used as a rectifier to allow the VCC supply for the converter to be derived from the clock The low current requirements of the AD (E3 mA) and the relatively high clock frequen- cies used (typically in the range of 10k-400 kHz) allows us- ing the small value filter capacitor shown to keep the ripple on the VCC line to well under of an LSB The shunt zener regulator can also be used in this mode This requires a clock voltage swing which is in excess of VZ A current limit for the zener is needed either built into the clock generator or a resistor can be used from the CLK pin to the Va pin Applications TLH5607 – 15 TLH5607 – 16 FIGURE 4 Operating with a Temperature Compensated Reference TLH5607 – 17 Note 45V s VCC s 63V FIGURE 6 Generally VCC from the Converter Clock FIGURE 5 Using the AD as the System Supply Regulator TLH5607 – 9 FIGURE 7 Remote SensingClock and Power on 1 Wire 13 |
