A suitable choice for the
bipolar transistor would be a
1V8
10uF
10uF
6.8nF 2.2uF ZTX749. It satisfies the
3V3
technical specification and
5V0
is very cost effective.

STMicroelectronics advises the use of a grounding star point. All
decoupling capacitors should be placed as close to sensor as
possible.
The support circuit outlined above describes a USB based
system with a nominal 5V supplying the device.
10.2 Transistor choice
The ZTX749 has a high min. HFE (lower on-chip current). It is also inexpensive and has good heat
dissipation.
10.3 Pin 1 and image orientation
Please note that for the sensor array to produce a correctly aligned image, pin 1 should be located
at the ‘top’ rather than 180 degrees rotated at the ‘bottom’ (see Figure 3).
