2 RELATED PRODUCTS FOS (Fiber optic plate coated with X-ray scintillator) The FOS is an optical device for X-ray imaging, fabricated by coating an X-ray scintillator material over a fiber optic plate consisting of tens of million glass fibers each a few micrometers in diameter. The FOS provides higher sensitivity and resolution than currently used sensitized paper films and also allows realtime digital radiography when directly coupled to a commercially available CCD. The fiber optic plate used in the FOS has excellent X-ray absorption characteristics, so that X-rays penetrating the X-ray scintillator and directly entering the CCD are minimized to less than 1 %. This protects the CCD from the deterioration and increased noise caused by X-ray irradiation, assuring a long service life and maintaining high image quality. Various sizes and shapes of FOS are available to meet your particular needs, including tapered FOP types. Structure "MEMORY STICK" is trademark of Sony Corporation.

13 Functional Description Power Supply Range series are provided with four line output level, which will permit on optimum overload margin for power supply conditions. And this series are designed to operate on either single supply or split supply. Table 1 Supply Voltage Item HA1174 HA1175 HA1177 Single supply 7.0 V to 16.0 V 8.0 V to 16.0 V 9.5 V to 16.0 V 1.0 V to 16.0 V Split supply GND level ±5.0 V to 8.0 V ±5.0 V to 8.0 V ±5.0 V to 8.0 V ±6.0 V to 8.0 V V EE level ±3.5 V to ±8.0 V ±4.0 V to 8.0 V ±4.8 V to 8.0 V ±6.0 V to 8.0 V A. The lower limit of supply voltage depends on the line output reference level. The minimum value of the overload margin is specified as 1 db by Dolby Laboratories. B. In case of using digital GND terminal referring to GND level, operating voltage range varies depending on the condition at power on. On using the /174/175, use within the following ranges to avoid latch-ups. When power on in mode: ±5.0 V to ±8.0 V When power on in NR-ON mode: ±5.7 V to ±8.0 V C. In the reverse-voltage conditions such as D-GND is higher than V CC or D-GND is lower than GND, excessive current flows into the D-GND to destory this IC. To prevent such destruction, pay attention to the followings on using. Single power supply : Short-circuit the D-GND and GND directory on the board mounting this IC. Split power supply : Avoid reverse conditions of D-GND and V CC or V EE voltage, including transient-time of power ON/OFF. Reference Voltage For the single supply operation these devices provide the reference voltage of half the supply voltage that is the signal grounds. As the peculiarity of these devices, the capacitor for the ripple filter is very small about 1/100 compared with their usual value. The Reference voltage are provided for the left channel and the right channel separately. The block diagram is shown as figure 1. Rev.1, Nov. 199, page 11 of 66

Voltages shown above are determined by internal circuits of LSI when take pin 0 (DGND pin) as reference pin. On split supply use, same V TH can be offered by connecting DGND pin to GND pin. This means that it can be controlled directly by microprocessor. But power supply should be over ±5 V, notwithstanding the prescription of table 1.. Each pins are on pulled down with 100 kω internal resistor. Therefore, it will be low-level when each pins are open. 3. Over shoot level and under shoot level of input signal must be the standardized (High: 5.3 V, Low: V) 4. When connecting microcomputer or Logic-IC with series directly, there is apprehension of rush-current under some transition timming of raising voltage or falling voltage at V CC ON/OFF. On using, connect protective resistors of 10 to kω to all the control pins. It is shown is test circuit on this data sheet. And pins fixed to low level should be preferably open. 5. Pay attention not to make digital GND voltage lower than GND voltage. Rev.1, Nov. 199, page 13 of 66

Note on Connecting with Tape Head to IC This IC has no internal resistor to give the DC bias current to equalizer amp., therefore the DC bias current will give through the head. This IC provides the Vref buffer output pin for Rch and Lch separately (has two Vref terminal). In case of use that the Rch and Lch reference of head are connected commonly, please use one of Vref terminals of IC (47 pin or 5 pin) for head reference. If both 47 pin and 5 pin of IC are connected, rush current give the great damage to IC. The application circuit is shown in figure 3. Rev.1, Nov. 199, page 14 of 66
