FEATURES
AD7746 DEVICE DESCRIPTION
Full-featured evaluation board for the AD7746
PC evaluation software for control and measurement
of the AD7746
USB interface and cable in kit
The AD7746 is a high resolution capacitance-to-digital converter
(CDC). The capacitance to be measured is connected directly to
the device inputs. The architecture features inherent high resolution (24 bits, no missing codes, up to 21-bit effective resolution),
high linearity (0.01%), and high accuracy (±4 fF factory calibrated).
The AD7746 capacitance input range is ±4 pF (changing); the
AD7746 can accept up to 17 pF common-mode capacitance (not
changing), which can be balanced by a programmable on-chip
digital-to-capacitance converter (CAPDAC).
APPLICATIONS
Capacitive length sensor demo
AD7746 performance evaluation
Platform to integrate the AD7746 into system design
EVALUATION BOARD DESCRIPTION
The AD7746 has two capacitive input channels. Each channel
can be configured as single-ended or differential. The AD7746
is designed for floating capacitive sensors. For capacitive sensors
with one plate connected to ground, the AD7747 is recommended.
This data sheet describes the evaluation board for the AD7746.
The evaluation board interfaces to the USB port of a PC. Evaluation
software is available with the evaluation board, which allows the
user to easily communicate with the AD7746.
The AD7746 has an on-chip temperature sensor with resolution
of 0.1°C and accuracy of ±2°C. The on-chip voltage reference
and the on-chip clock generator eliminate the need for any
external components in most capacitive sensor applications.
The part has a standard voltage input, which, together with the
differential reference input, allows easy interface to an external
temperature sensor such as an RTD or diode.
Note that the AD7746 evaluation board software should be
installed before connecting the AD7746 evaluation board to
the PC.
To properly use the evaluation board, see the AD7746 data sheet
on the Analog Devices, Inc., website. You can download the data
sheet from www.analog.com/AD7746.

EVALUATION BOARD HARDWARE
POWER SUPPLIES
External Connection—USB
The board is powered via the 5 V supply from the USB connector, J1, indicated via LED D1 (POWER). The 5 V supply can be
used to power the AD7746 directly. A 3.3 V regulated voltage from
the on-board ADP3303 high precision, low power, 3.3 V output
voltage regulator can also be used. Alternatively, the AD7746 can
be powered using an external 3 V or 5 V power supply via J2.
The AD7746 evaluation board allows customers to connect
their own specific AD7746 application board to Pin 4, Pin 6,
and Pin 8 of LK2. Using the PC evaluation software, customers
can evaluate their application hardware using the AD7746
evaluation board as a USB-to-I2C digital interface only, as
shown in Figure 7.

USB CONNECTOR
SOCKETS
A standard USB connector, J1, is used to connect the evaluation
board to the USB port of a PC. A standard USB connector cable
is included with the AD7746 evaluation kit. Because the board
is powered by the USB connector, an external power supply is
not required, although one can be connected to J2.
The AD7746 evaluation board has four populated sockets:
EXCA (P1), EXCB (P2), CIN1− (P3), and CIN1+ (P4). The
functions of these sockets are described in Table 1.
Communication between the AD7746 evaluation board and the
PC is over the USB interface. The on-board USB controller
controls this communication.
To interface to the AD7746 using the analog voltage input
channel or the external temperature sensor and an external
voltage reference, use the unpopulated through hole pads
labeled AIN+, AIN−, REF+, and REF− located on the AD7746
evaluation board.

EVALUATION BOARD SOFTWARE
CONFIGURING THE EVALUATION BOARD
The evaluation board is initially configured to allow the user to
interface any capacitive input directly to CIN1 of the AD7746
device. To do this, connect one end of the capacitive input to
the SMB connector labeled CIN1+ or CIN1−. Then connect the
other end of the capacitive input to the SMB connector labeled
EXCB.
The AD7746 provides a second capacitive channel, CIN2. On
the AD7746 evaluation board, the second capacitive channel
is used with the on-board capacitive length sensor demo.
GETTING STARTED WITH THE SOFTWARE
To run the AD7746 evaluation board software, follow these steps:
1.
From the Start menu, select Program Files > Analog
Devices\AD7746 Evaluation Software.
The AD7745/AD7746 Evaluation Software window
appears (see Figure 9). By default, the application opens
to the Real Time tab.
2.
Click the Length Demo (CH2) button. This action enables
continuous conversions on Capacitive Channel 2 in singleended mode, enables EXCA as the excitation output pin, sets
the update rate, and initializes CAPDAC A. The Capacitive
Length Sensor Demo window appears (see Figure 10).
05513-004
To disable the capacitive length sensor demo, disconnect the two
0 Ω SMD resistors, R1 and R2. Any capacitive sensor can then be
directly interfaced to CIN2 of the AD7746 by connecting one end
of the capacitive input to either of the SMB connectors labeled
CIN2+ or CIN2− and the other end to one of the SMB connectors
labeled EXCA or EXCB.
Note that after the capacitive length sensor demo is disabled,
either of the excitation output pins (EXCA or EXCB) can be
used as the excitation source, regardless of which capacitive
channel is enabled. These settings are configurable using the
evaluation board software.

4.
Slide the ruler on the evaluation board. This action is
mirrored on the screen. The code, capacitance, and length
(in inches or mm) appear on the right side of the window
(see Figure 10). These values change as you slide the ruler
on the evaluation board.
Remove the ruler completely by clicking the 0 mm/0 inch
Cal button.
5.
6.
Place the ruler at the 51 mm/2 inch mark by clicking the
51 mm/2 inch Cal button. The part is now calibrated to
the length of the ruler. Note that when the ruler length
exceeds 80 mm, the demo can no longer measure the ruler
length because the input capacitance range (±4 pF) has
been exceeded.
Click BACK to return to the Real Time tab.
