| IMAGE SENSOR Flat panel sensor C9728DK-10 Cassette type X-ray sensor with USB 2.0 interface Features Applications l Low noise: 80 electrons l High quality image: 1032 x 1032 pixels l Pixel size: 50 x 50 m l Digital output: 14-bit USB 2.0 interface l High-speed imaging: 3 frames/s l Supports HAMAMATSU API (DCAM-API). l Diffraction l Radiography s Block diagram C9728DK-10 is a lightweight and compact flat panel sensor consisting of a sensor board and a control board. The sensor board also has 8 charge-sensitive amplifier arrays each having 132 channel amplifiers with a horizontal shift register. Analog video signals are amplified as the charge on each video line by 1056 ch charge amplifiers with CDS (Correlated Double Sampling) circuits added, and are output each of 8 amplifier arrays.

The south bridge of on-board Intel chip set should be ICH4 or later. * Power source: A.vdd = +5.0 0.1 V (600 mA), D.vdd = +5.0 0.1 V (900 mA) Please use a low noise series power supply. (Avoid using a switching power supply.) A pigtail power cable (terminated with a JST J-C9-2C plug at one end and open at the other end; 2 m; see Table 1.), an trigger cable (terminated with an FGG.0B. 304. CLAD56 plug at one end and open at the other end; 5 m; see table 2.) and an earth cable (AWG 18; 4 m) come supplied with C9728DK10. The voltages described above are specified at the flat panel sensor side. The impedance of the power cable attached with the flat panel sensor is low enough but it causes 0.1 V approx. drop. Therefore the voltage at the power source side should be set 0.1 V higher than the voltage specified above. Install a noise filter on the AC power input line to prevent surges on the AC line. DCAM-API (Digital Camera Application Programming Interface) produced by HAMAMATSU supports C9728DK-10. The driver software and DLL are included in DCAM-API. The latest version of the DCAM-API can be downloaded from http://www.dcamapi.com/ . DCAM-SDK which includes function manual and sample software can be provided only for OEM customer. The USB receptacle is mini-B type. The mini-B USB cable is not attached. The earth terminal must be connected to a stable earth point to eliminate noise from surroundings.

(Strong shock such as drop impacts may cause permanent damage to these sensors.) * Users must take responsibility for implementing X-ray shielding safety measures to avoid the risk of X-ray exposure. * The specification listed in this datasheet is defined at the time of shipment. Characteristics may vary somewhat due to exposure to X-rays so take proper countermeasures such as making periodic image correction. * This product is warranted for a period of 12 months after the date of the shipment. The warranty is limited to replacement or repair of any defective product due to defects in workmanship or materials used in manufacture. The warranty does not cover loss or damage caused by natural disaster, misuse (including modifications and any use not complying with the environment, application, usage and storage conditions described in this datasheet), or total radiation dose over 45000 Roentgen (less than 18 keV) even within the warranty period. Information furnished by HAMAMATSU is believed to be reliable. However, no responsibility is assumed for possible inaccuracies or omissions. Specifications are subject to change without notice. No patent rights are granted to any of the circuits described herein. (c)2007 Hamamatsu Photonics K.K.
