GENERAL DESCRIPTION
The ADPD2140 is an optical sensor that measures the angle of
incident infrared light. Light angles calculated from the ADPD2140
response are linear to ±5° within an angular field of view of ±35°.
The ADPD2140 has a radiant sensitive area of 0.31 mm2. The
low junction capacitance and low dark current of the ADPD2140
allows optimal integration with the ADPD1080 photometric
front end. The ADPD2140 can be used with a synchronous
infrared light source such as a light emitting diode (LED) to
detect user hand movements for gesture recognition. The
ADPD2140 requires four photodiode channels. Therefore, use
the ADPD1080BCPZ with the ADPD2140.
Packaged in a small, clear mold, 2 mm × 3 mm, 8-lead LFCSP,
the ADPD2140 is specified over the −40°C to +85°C operating
temperature range.

THEORY OF OPERATION
ANGULAR RESPONSE
The ADPD2140 consists of arrays of silicon p-type, intrinsic,
n-type (PIN) photodiodes that provide a linear measurement of
incident infrared light angle. There are four separate channels on
the ADPD2140, each corresponding to one photodiode.
The ADPD2140 enables a 2-axis light angle measurement, in
both the x and y direction. To calculate angles in the x and y
direction with respect to the sensor use the four photodiode
channels (xL, xR, yT, and yB) and the following equations:
x = (xL − xR)/(xL + xR) (1)
y = (yT − yB)/(yT + yB) (2)
The resulting quantities (x and y) are ratios related to angles
through a constant term, M. Calculate angles in the horizontal and
vertical direction by dividing x and y by the constant term, M
(see Table 1). Angles measured by the ADPD2140 are linear to ±5°
within an angular field of view of ±35° and zero crossing offset at
±5°, as seen in Figure 9. The directionality when using Equation 1
and Equation 2 is shown in Figure 10, which indicates positive
angles in the x and y directions.

Figure 10. Directionality Response
The ADPD2140 is typically used in conjunction with a LED or
laser emitter operating at a near infrared wavelength. The
ADPD2140 provides light angle measurement without the need
for an external lens. An external lens is neither required nor
recommended for operation.
An integrated visible light blocking optical filter on the ADPD2140
provides built in rejection of unwanted visible ambient light
signals, such as sunlight and indoor lighting. Figure 7 shows the
combined responsivity of the ADPD2140 with the integrated
optical filter.
The low junction capacitance and low dark current of the
ADPD2140 allows optimal integration with the ADPD1080
photometric front end. This complete solution offers additional
ambient light rejection, low power operation, and analog-to-digital
conversion of the ADPD2140 analog signals.
TYPICAL CONNECTION DIAGRAM
Figure 11 shows the ADPD2140 connections with the ADPD1080
photometric front end. With up to eight photodiode input
channels, the ADPD1080 is a preferred choice for the analog
front end for interfacing with the ADPD2140. In this configuration,
the ADPD2140 and ADPD1080 solution can operate using
synchronous LED pulses to detect the angle of light reflected from
objects or used in ambient measurement mode to provide a
measure of the incident angle of an ambient or other unsyn-
chronized light source. For reference, the optimal choice of
reverse bias for typical operation with the ADPD2140 is 0.2 V.

APPLICATIONS INFORMATION
GESTURE RECOGNITION
The unique angular response of the ADPD2140 coupled with
the high performance ambient light rejection of the ADPD1080
enables a robust and effective implementation of gesture
recognition. The following algorithm demonstrates recognition
of up, down, left, right, and click hand gestures based on data
from the four channels of the ADPD2140:
1. Prior to operation of the ADPD2140 and the ADPD1080
for gesture recognition, calibrate the ADPD1080 clocks. See
the ADPD1080 data sheet for more information on how to
calibrate the 32 kHz and 32 MHz clocks.
2. Set the ADPD1080 mode of operation to sample mode by
writing 0x2 to Register 0x10, Bits[1:0].
3. Collect the data measured by the device. See the ADPD1080
data sheet for instructions on how to read data from registers
using the first in, first out (FIFO) and interrupts. Data is
available directly from data registers or from the 128-byte
FIFO in Register 0x60, Bits [15:0].
4. The data in the four output channels of the ADPD1080
calculates the angle of incident light. After the xL, xR, yT,
and yB data are collected, calculate the angles and intensity
with the following equations:
Horizontal angle: x = (xL – xR)/(xL + xR)
Vertica l ang le: y = (yT – yB)/(yT + yB)
Intensity: L = xL + xR + yT + yB
5. Prior to gesture event detection, offsets of the ADPD1080
must be digitally subtracted from each channel. These offsets
are not due to photodiode dark current and are set by the
ADPD1080 on-chip analog-to-digital converter (ADC).
Register 0x18, Register 0x19, Register 0x1A, and
Register 0x1B contain the ADC offsets for Timeslot A,
while Register 0x1A, Register 0x1B, Register 0x1E, and
Register 0x1F contain the ADC offsets for Timeslot B. The
nominal value for all offsets is 0x2000. To modify these offsets,
measure the 16-bit output of each channel, in ADC codes,
and add it to the existing 16-bit number in the ADC offset
register, SLOTx_CHx_OFFSET (nominally 0x2000). Then,
write to the ADC offset register with this result. When the
offsets are correctly subtracted, the intensity reading L is
close to zero codes with no objects in the sensor field of view.
6. The start of a gesture event can be defined as occurring
when intensity data crosses a preset threshold. Nominally,
this threshold must be set to 1000 codes. However, the
threshold can be adjusted to suit the application.
7. The end of a gesture event can then be defined as the number
of samples after which the intensity drops back below the
preset threshold, past a certain minimum number of samples
(nominally five samples).
8. Use the start and stop points of the gesture event to
determine whether the gesture was up, right, left, down, or
a click. For more detail on this process, see the following
pseudocode:
event = False
intensityThreshold = 1000 (should be
adjustable by the user)
clickThreshold = 0.07 (should be adjustable
by the user)
if event = True:
i += 1
if i >= 5 and L < intensityThreshold:
event = False
gestureStopX = x
gestureStopY = y
m = (gestureStartY –
gestureStopY)/(gestureStartX – gestureStopX
+ 1e-6)
d = sqrt((gestureStartX – gestureStopX)^2 +
(gestureStartY – gestureStopY)^2)
if d < clickThreshold:
gesture = ‘CLICK’
else:
if abs(m) > 1:
if gestureStartY >
gestureStopY:
gesture = ‘UP’
else:
gesture = ‘DOWN’
elif abs(m) < 1:
if gestureStartX >
gestureStopX:
gesture = ‘LEFT’
else:
gesture = ‘RIGHT’
else:
if L > intensityThreshold:
i = 0
event = True
gestureStartX = x
gestureStartY = y

OBJECT TRIANGULATION
While a single ADPD2140 allows for measurement of the x and
y coordinates of an object or light source, two ADPD2140 placed
at a distance apart can calculate the z distance using triangulation.
The superscripted A and B refer to ADPD2140 sensors that are
measured in Timeslot A and Timeslot B of the ADPD2140.
Calculate the triangulation distance z as follows:
If sign(yA) = sign(yB),
2
)–(
BA
yy
C
z=
Or, if sign(yA) ≠ sign(yB),
2
)(

yy

z

=
C is an empirically determined proportionality constant that
depends on the baseline distance between the two angle diodes,
which converts the x and y measurements to angles, in radians.
For reference, the baseline distance, c, between both angle diodes is
equal to 1” on the E VA L -ADPD2140Z evaluation board. This
quantity sets the units of the final distance measurement output.
Figure 12 shows the operation of a typical triangulation
measurement using the ADPD2140.
