Evaluation Board for the AD7190/AD7192
4.8 kHz Ultralow Noise 24-Bit Sigma-Delta ADCs
FEATURES
GENERAL DESCRIPTION
Full-featured evaluation board for the AD7190/AD7192
Standalone interface using microcontroller and LCD display
PC software for control of AD7190/AD7192 using USB
interface
Various linking options
The AD7190/AD7192 evaluation kit is a powerful tool for
exploring and evaluating the AD7190/AD7192 features.
INTRODUCTION
When the board is connected to (and possibly powered from) a
PC via a standard USB interface, the PC software allows the
graphical display of real-time data, logs them into a text file,
allows you to modify the AD7190/AD7192 internal settings,
and generally helps in understanding the part features and
performance.
The evaluation board can be operated in complete standalone,
battery-powered mode. The LCD display is used to display the
conversion data.
This user guide describes the evaluation board for the AD7190/
AD7192, which are 4.8 kHz ultralow noise 24-bit sigma-delta
(Σ-Δ) ADCs. The AD7190/AD7192 are complete analog front
ends for low frequency measurement applications. The parts
contain two differential inputs/four pseudo differential inputs,
and include a low noise instrumentation amplifier, reference
detect, and a low-side power switch.
Finally, the board’s flexible interface structure allows it to be
connected in a number of useful configurations. For example,
the digital section of the evaluation board can be used independently as a convenient digital interface for a user’s own
sensor design PCB or module containing the AD7190/AD7192.
Alternatively, an external microcontroller can be interfaced to
the AD7190/AD7192 and thus the evaluation board can act as a
complete analog front end for creating and debugging software
on the user’s own digital platform.
Full data on the AD7190/AD7192 is available in the AD7190
and AD7192 data sheets available from Analog Devices, Inc.,
and should be consulted in conjunction with this user guide
when using the evaluation board.

EVALUATION BOARD HARDWARE
POWER SUPPLIES
There are several power supply options on the AD7190/AD7192
evaluation board.
Connected to USB Connector
The AD7190/AD7192 evaluation board is powered via the 5 V
supply from the USB connector, J51. This 5 V supply can be
used to power the AD7190/AD7192 directly. Link J1 should be
placed in Position 5 V USB.
The 5 V supply from the USB connector can be regulated to
3.3 V using the on-board ADP3303-3, a high precision, low
power, 3.3 V output voltage regulator. Therefore, using Link J1,
the 3.3 V can be used as the power supply to the AD7190/AD7192.
Link J1 should be placed in Position 3.3 V.
The AD7190/AD7192 can be powered using a 9 V battery, B1,
or using an external 9 V dc source connected at J31. The 9 V is
regulated down to 5 V using the on-board ADP3303-5, a high
precision, low power 5 V output regulator. Using Link J1, this
regulated 5 V can be used as the supply to the AD7190/AD7192.
To use this option, Link J1 should be placed in Position 5 V BAT.
An external power supply can be applied via J10. Link J1 should
be placed in Position EXT.
Standalone Operation
The AD7190/AD7192 evaluation board can be powered using a
9 V battery, B1, or using an external 9 V dc source connected at
J31. The 9 V is regulated down to 5 V using the on-board
ADP3303-5, a high precision, low power 5 V output regulator.
Using Link J1, this regulated 5 V can be used as the supply to
the AD7190/AD7192. To use this option, Link J1 should be
placed in Position 5 V BAT.
An external power supply can be applied via J10. Link J1 should
be placed in Position EXT.

Figure 3. Noise Test Connections
As shown in Figure 3, inserting the links in Header J3 connects
a resistor network to the AD7190/AD7192. The reference to
the ADC is provided by AVDD. The resistor divider generates
a bias voltage of approximately AVDD/2. Channel AIN1 and
Channel AIN2 are connected to this voltage. Therefore, conversions can now be performed using this external short to measure
the rms noise, peak-to-peak noise, and peak-to-peak resolution.

USING THE AD7190/AD7192 EVALUATION BOARD IN STANDALONE MODE
The AD7190/AD7192 evaluation board can be operated in
standalone mode. In this mode, the evaluation board functions
as a weigh scale demonstration. Channel AIN3/AIN4 is the
analog input channel with REFIN1(+)/REFIN1(−) as the reference source. These analog input pins and reference pins are
connected to the J4 header along with AVDD and GND. This
header allows the user to connect a load cell to the AD7190/
AD7192. The load cell should be connected to the header, as
shown in Figure 5. A 6-wire load cell is shown, but a 4-wire load
cell can also be connected.

The AD7190/AD7192 are configured for an output data rate of
4.69 Hz. The gain is programmed to 128. Channel AIN3/AIN4
is selected as the active channel with REFIN1(+)/REFIN1(−)
selected as the reference source.
The conversions from the AD7190/AD7192 are displayed on
the LCD display. The four buttons beneath the LCD display
allow the user to calibrate the weigh scale system, adjust the
LCD contrast, and display the results in code or weight. The
function of each button is listed at the bottom of the LCD
display.
To operate the weigh scale demonstration, connect the load cell
to Header J4 as shown in Figure 5. Apply power to the AD7190/
AD7192 evaluation board using either a 9 V battery or a 9 V dc
power source. Ensure that Link J1 is in Position 5 V BAT/EXT.
The weigh scale demonstration can also be powered from the
USB connector if the board is connected to a PC. Link J1 should
be in Position 5 V USB in this case.
With no weight on the weigh scale, an offset calibration should
be performed (selectable from the buttons below the LCD
display). The expected full-scale weight should then be placed
on the load cell and the full-scale calibration performed. The
user should select the corresponding full-scale weight on the
LCD display as the weigh scale demonstration supports fullscale weights of 500 g to 10 kg. The software then continuously
reads conversions from the AD7190/AD7192, scales the conversions appropriately, and displays the resulting weight on the
LCD display.
