TSL1401CL − Detailed Description
Detailed Description
The sensor consists of 128 photodiodes arranged in a linear
array. Light energy impinging on a photodiode generates
photocurrent, which is integrated by the active integration
circuitry associated with that pixel.
During the integration period, a sampling capacitor connects
to the output of the integrator through an analog switch. The
amount of charge accumulated at each pixel is directly
proportional to the light intensity and the integration time.
The output and reset of the integrators is controlled by a 128-bit
shift register and reset logic. An output cycle is initiated by
clocking in a logic 1 on SI. For proper operation, after meeting
the minimum hold time condition, SI must go low before the
next rising edge of the clock. An internal signal, called Hold, is
generated from the rising edge of SI and transmitted to analog
switches in the pixel circuit. This causes all 128 sampling
capacitors to be disconnected from their respective integrators
and starts an integrator reset period. As the SI pulse is clocked
through the shift register, the charge stored on the sampling
capacitors is sequentially connected to a charge-coupled
output amplifier that generates a voltage on analog output AO.
Simultaneously, during the first 18 clock cycles, all pixel
integrators are reset, and the next integration cycle begins on
the 19 th clock. On the 129th clock rising edge, the SI pulse is
clocked out of the shift register and the analog output AO
assumes a high impedance state. Note that this 129 th clock
pulse is required to terminate the output of the 128th pixel, and
return the internal logic to a known state. If a minimum
integration time is desired, the next SI pulse may be presented
after a minimum delay of t qt (pixel charge transfer time) after
the 129 th clock pulse.
AO is an op amp-type output that does not require an external
pull-down resistor. This design allows a rail-to-rail output
voltage swing. With V DD = 5V, the output is nominally 0V for no
light input, 2V for normal white level, and 4.8V for saturation
light level. When the device is not in the output phase, AO is in
a high-impedance state.

TSL1401CL − Detailed Description
The voltage developed at analog output (AO) is given by:
Vout = Vdrk + (Re) (Ee) (t int)
where:
• V out is the analog output voltage for white condition
• V drk is the analog output voltage for dark condition
• R e is the device responsivity for a given wavelength of
light given in V/(μJ/cm2)
• E e is the incident irradiance in μW/cm 2
• t int is integration time in seconds
A 0.1μF bypass capacitor should be connected between VDD
and ground as close as possible to the device.
The TSL1401CL is intended for use in a wide variety of
applications, including: image scanning, mark and code
reading, optical character recognition (OCR) and contact
imaging, edge detection and positioning, and optical linear and

TSL1401CL − Principles of Operation
Principles of Operation
Integration Time
The integration time of the linear array is the period during
which light is sampled and charge accumulates on each pixel’s
integrating capacitor. The flexibility to adjust the integration
period is a powerful and useful feature of the ams TSL14xx linear
array family. By changing the integration time, a desired output
voltage can be obtained on the output pin while avoiding
saturation for a wide range of light levels.
The integration time is the time between the SI
(Start Integration) positive pulse and the HOLD positive pulse
minus the 18 setup clocks. The TSL14xx linear array is normally
configured with the SI and HOLD pins tied together. This
configuration will be assumed unless otherwise noted. Sending
a high pulse to SI (observing timing rules for setup and hold to
clock edge) starts a new cycle of pixel output and integration
setup. However, a minimum of (n+1) clocks, where n is the
number of pixels, must occur before the next high pulse is
applied to SI. It is not necessary to send SI immediately on/after
the (n+1) clocks. A wait time adding up to a maximum total of
100ms between SI pulses can be added to increase the
integration time creating a higher output voltage in low light
applications.
Each pixel of the linear array consists of a light-sensitive
photodiode. The photodiode converts light intensity to a
voltage. The voltage is sampled on the Sampling Capacitor by
closing switch S2 (position 1) (see Figure 2). Logic controls the
resetting of the Integrating Capacitor to zero by closing switch
S1 (position 2).
At SI input, all of the pixel voltages are simultaneously scanned
and held by moving S2 to position 2 for all pixels. During this
event, S2 for pixel 1 is in position 3. This makes the voltage of
pixel 1 available on the analog output. On the next clock, S2 for
pixel 1 is put into position 2 and S2 for pixel 2 is put into
position 3 so that the voltage of pixel 2 is available on the
output.
Following the SI pulse and the next 17 clocks after the SI pulse
is applied, the S1 switch for all pixels remains in position 2 to
reset (zero out) the integrating capacitor so that it is ready to
begin the next integration cycle. On the rising edge of the 19 th
clock, the S1 switch for all the pixels is put into position 1 and
all of the pixels begin a new integration cycle.
The first 18 pixel voltages are output during the time the
integrating capacitor is being reset. On the 19th clock following
an SI pulse, pixels 1 through 18 have switch S2 in position 1 so
that the sampling capacitor can begin storing charge. For the
period from the 19 th clock through the nth clock, S2 is put into
position 3 to read the output voltage during the nth clock. On
the next clock the previous pixel S2 switch is put into position 1
Page 14
Document Feedback
ams Datasheet
[v1-00] 2016-Jun-21
TSL1401CL − Principles of Operation
to start sampling the integrating capacitor voltage. For
example, S2 for pixel 19 moves to position 1 on the 20 th clock.
On the n+1 clock, the S2 switch for the last (n th) pixel is put into
position 1 and the output goes to a high-impedance state.
If a SI was initiated on the n+1 clock, there would be no time
for the sampling capacitor of pixel n to charge to the voltage
level of the integrating capacitor. The minimum time needed
to guarantee the sampling capacitor for pixel n will charge to
the voltage level of the integrating capacitor is the charge
transfer time of 20μs. Therefore, after n+1 clocks, an extra 20μs
wait must occur before the next SI pulse to start a new
integration and output cycle.
The minimum integration time for any given array is determined
by time required to clock out all the pixels in the array and the
time to discharge the pixels. The time required to discharge the
pixels is a constant. Therefore, the minimum integration period
is simply a function of the clock frequency and the number of
pixels in the array. A slower clock speed increases the minimum
integration time and reduces the maximum light level for
saturation on the output. The minimum integration time shown
in this data sheet is based on the maximum clock frequency of
8MHz.
The minimum integration time can be calculated from the
equation:
1
T int ( min ) =  ------------------------------------------------------------------------- × ( n – 18 ) pixels + 20μs
maximum clock frequency
where:
n is the number of pixels
In the case of the TSL1401CL with the maximum clock frequency
of 8MHz, the minimum integration time would be:
Tint(min) = 0.125μs × (128 - 18) + 20μs = 33.75μs
It is good practice on initial power up to run the clock (n+1)
times after the first SI pulse to clock out indeterminate data
from power up. After that, the SI pulse is valid from the time
following (n+1) clocks. The output will go into a
high-impedance state after the n+1 high clock edge. It is good
practice to leave the clock in a low state when inactive because
the SI pulse required to start a new cycle is a low-to-high
transition.
The integration time chosen is valid as long as it falls in the
range between the minimum and maximum limits for
integration time. If the amount of light incident on the array
during a given integration period produces a saturated output
(Max Voltage output), then the data is not accurate. If this
occurs, the integration period should be reduced until the
analog output voltage for each pixel falls below the saturation
level. The goal of reducing the period of time the light sampling
ams Datasheet
[v1-00] 2016-Jun-21

Document Feedback
TSL1401CL − Principles of Operation
window is active is to lower the output voltage level to prevent
saturation. However, the integration time must still be greater
than or equal to the minimum integration period.
If the light intensity produces an output below desired signal
levels, the output voltage level can be increased by increasing
the integration period provided that the maximum integration
time is not exceeded. The maximum integration time is limited
by the length of time the integrating capacitors on the pixels
can hold their accumulated charge. The maximum integration
time should not exceed 100ms for accurate measurements.
It should be noted that the data from the light sampled during
one integration period is made available on the analog output
during the next integration period and is clocked out
sequentially at a rate of one pixel per clock period. In other
words, at any given time, two groups of data are being handled
by the linear array: the previous measured light data is clocked
out as the next light sample is being integrated.
Although the linear array is capable of running over a wide
range of operating frequencies up to a maximum of 8MHz, the
speed of the A/D converter used in the application is likely to
be the limiter for the maximum clock frequency. The voltage
output is available for the whole period of the clock, so the
setup and hold times required for the analog-to-digital
conversion must be less than the clock period.

TSL1401CL − Soldering Information
The CL package has been tested and has demonstrated an
ability to be reflow soldered to a PCB substrate.
Soldering Information
The solder reflow profile describes the expected maximum heat
exposure of components during the solder reflow process of
product on a PCB. Temperature is measured on top of
component. The components should be limited to a maximum
of three passes through this solder reflow profile.

TSL1401CL − Storage Information
Storage Information
Moisture Sensitivity
Optical characteristics of the device can be adversely affected
during the soldering process by the release and vaporization of
moisture that has been previously absorbed into the package.
To ensure the package contains the smallest amount of
absorbed moisture possible, each device is dry-baked prior to
being packed for shipping. Devices are packed in a sealed
aluminized envelope called a moisture barrier bag with silica
gel to protect them from ambient moisture during shipping,
handling, and storage before use.
The CL package has been assigned a moisture sensitivity level
of MSL 5a and the devices should be stored under the following
conditions:
• Temperature Range: 5°C to 50°C
• Relative Humidity: 60% maximum
• Total Time: 6 months from the date code on the
aluminized envelope - if unopened
• Opened Time: 24 hours or fewer
Rebaking will be required if the devices have been stored
unopened for more than 6 months or if the aluminized envelope
has been open for more than 24 hours. If rebaking is required,
it should be done at 60°C for 24 hours.
