| A 1nF capacitor should be connected to brightness control, pin 19, to prevent possible oscillations. A block diagram is shown in figure 1. For the AD53013JRP a DATA ENABLE is used instead of the 35th output. The DATA ENABLE input is a metal option for the AD53013JRP. The output current is typically 20 times greater than the current into pin 19, which is set by an external variable resistor. There is an internal limiting resis- tor of 400Ω nominal value. Figure 2 shows the input data format. A start bit of logical "1" precedes the 35 bits of data. At the 36th clock a LOAD signal is generated synchronously with the high state of the clock, which loads the 35 bits of the shift registers into the latches. |

| The AD53013JRP is a high sensitive and low dark current 128−elements linear image sensor which includes CCD drive circuit, clamp circuit and sample & hold circuit. The CCD drive circuit consists of the pulse generator therefore it is possible to easy drive by applying simple pulses. The sensor is designed for scanner. |
