5.3 ELECTRICAL
Location Accuracy:
Linearity:
±2.5mm Measured over 9 points (See note 1)
1.5%
Current Consumption:
20mA max at DC 5V when applying 5VDC between pins 3 & 5
Switch Bounce (Chattering): 10ms min when using the silicon rubber measurement rod.
Insulation resistance:
10MΩ minimum at 25KV DC applied between pins 3 & 7 or
between 5 and 7
Dielectric Strength:
25KV DC for 1 minute
Note 1:
Measurement condition of linearity is corrected within the
control IC. In general the location accuracy is specified
as follows:
Actual co-ordinate point - theoretical co-ordinate point
= location accuracy.
Theoretical
Error
In general a 9 point co-ordinate calibration system is used
to adjust the micro controller accuracy. (20 point can be
used in combination with an EEPROM design).
Note 2:
Actual
Distance
Pins 3, 5 and 7 are the glass and film connection points.

5.5 PEN LIFE
Character Writing life:
Touch Input life :
Note 1:
1,000,000 words minimum
10,000,000 times minimum
Effective input area
Words are written in the notes area and the size of the word is
7.5mm x 6.75mm. A word is any Alphabet / Number / Mark.
The pen is as shown below and applies a force of 250g.
A failure is judged to happen when the current consumption or
insulation resistance or dielectric strength are not met as
shown in 5.3. The location accuracy with 9 point calibration
must be ±4.4 mm max.
