The TSL1406R is a 400 dots-per-inch (DPI) linear
sensor array consisting of two 384-pixel sections,
each with its own output. The sections are aligned
to form a contiguous 768 × 1 pixel array. The
device incorporates a pixel data-hold function that
provides simultaneous integration-start and
integration-stop times for all pixels.
Pixels measure 63.5 μm by 55.5 μm, with 63.5-μm center-to-center spacing and 8-μm spacing between pixels.
Operation is simplified by internal logic that requires only a serial-input (SI) pulse and a clock.
The device operates from a single 5-V power source. The two sections of 384 pixels each can be read out
separately or can be cascaded to provide a single output for all 768 pixels (see Figure 9).
The TSL1406RS is the same device mounted in a shorter package. These devices are intended for use in a
wide variety of applications including mark and code reading, OCR and contact imaging, edge detection and
positioning, and optical encoding.

Detailed Description

Ground (substrate). All voltages are referenced to GND.
The sensor consists of 768 photodiodes, called pixels, arranged in a linear array. Light energy impinging on a
pixel generates photocurrent that is then 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 on that pixel
and the integration time.
Te
ch
ni
ca
The output and reset of the integrators are controlled by a 384-bit shift register and reset logic. An output cycle
is initiated by clocking in a logic 1 on SI. Another signal, called HOLD, is generated from the rising edge of SI1
when SI1 and HOLD1 are connected together. This causes all 384 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. The integrator reset period ends 18 clock cycles after
the SI pulse is clocked in. Then the next integration period begins. On the 384th clock rising edge, the SI pulse
is clocked out on the SO1 pin (section 1) and becomes the SI pulse for section 2 (when SO1 is connected to
SI2). The rising edge of the 385th clock cycle terminates the SO1 pulse, and returns the analog output AO of
section 1 to high-impedance state. Similarly, SO2 is clocked out on the 768th clock pulse. Note that a 769th clock
pulse is needed to terminate the SO2 pulse and return AO of Section 2 to the high-impedance state. If a minimum
integration time is desired, the next SI pulse may be presented after a minimum delay of tqt (pixel charge transfer
time) after the 769th clock pulse. Sections 1 and 2 may be operated in parallel or in serial fashion.

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 VDD = 5 V, the output is nominally 0 V for no light input, 2 V for normal white level, and 4.8 V
for saturation light level. When the device is not in the output phase, AO is in a high-impedance state.

TAOS042D − APRIL 2007
APPLICATION INFORMATION
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 TAOS 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.
lv
al
id
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 100 ms between SI pulses can be added to increase the integration time creating a higher output voltage
in low light applications.
am
lc s
on A
te G
nt
st
il
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 the
Functional Block Diagram on page 1). 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 19th 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 19th 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 to start sampling
the integrating capacitor voltage. For example, S2 for pixel 19 moves to position 1 on the 20th clock. On the n+1
clock, the S2 switch for the last (nth) pixel is put into position 1 and the output goes to a high-impedance state.
ni
ca
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 20 μs.
Therefore, after n+1 clocks, an extra 20 μs wait must occur before the next SI pulse to start a new integration
and output cycle.
Te
ch
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 8 MHz.

In the case of the TSL1406RS with the maximum clock frequency of 8 MHz, the minimum integration time would
be:

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 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 100 ms 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 8 MHz, 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.
