redundancy. If this function is required, solder a 0 Ω, 0402 size
resistor to the unpopulated resistor footprints (see Figure 17 for
more details), and move SL22 and SL23 to Position A.
Figure 2 shows these connectors to the ADC input terminals.
Each analog input differential pair has a second-order RC filter
option and common-mode option to center the input signal at
(AVDD1 + AVSSx)/2. An option is available to place an
additional VCM buffer in U8 to add drive strength and also
gain, attenuation, or filtering to this VCM signal. Channel 7 has
the option to evaluate an external drive amplifier using an
amplifier surfboard, to be plugged on J7/J10. The SL3, SL4,

EVALUATION BOARD HARDWARE
DEVICE DESCRIPTION
The AD7770, AD7771, and AD7779 is an 8-channel,
simultaneously sampled, 24-bit, Σ-Δ ADC with an additional
diagnostics 12-bit SAR. The AD7770, AD7771, and AD7779
offers one ADC per channel with synchronized sampling.
To cater to application specific ADC power scaling requirements,
the user can select either the high resolution mode or low power
mode. In high resolution mode, the AD7770 operates at 32 kSPS
maximum, the AD7771 operates at 128 kSPS maximum, and the
AD7779 operates at 16 kSPS maximum. In low power mode, the
AD7770 operates at 8 kSPS maximum, the AD7771 operates at
32 kSPS, and the AD7779 operates at 8 kSPS maximum.
The AD7770, AD7771, and AD7779 also provides a low latency,
sinc3 filter for digital filtering. The notches of the digital filter
are automatically set to remove harmonics at the sampling
frequency and the programmable gain amplifier (PGA)
chopping frequency.
The sample rate converter allows the user to fine tune the
decimation rate to maintain a number of samples per line cycle
for varying input frequencies. Choosing a low output data rate
increases the dynamic range, reducing the noise. Decimation
rates can be programmed via the AD777x evaluation software.
Embedded analog functionality on each ADC channel eases
system design. The AD7770, AD7771, and AD7779 has a fully
buffered PGA on each channel to reduce analog input current.
The AD7770, AD7771, and AD7779 also has a reference buffer
on each channel, with different operation modes to minimize
both the input current from the reference and the reference
noise.
Full specifications for the AD7770, AD7771, or AD7779 are
available in the AD7770, AD7771, or AD7779 data sheets and
should be consulted in conjunction with this user guide when
working with the evaluation board. Full details on the EVALSDP-CH1Z are available on the Analog Devices, Inc., website at
http://www.analog.com/eval-SDP-H1.
HARDWARE LINK OPTIONS
The default power link options are listed in Table 1, Table 2, and
Table 3. The evaluation board can be powered by different
sources, as described in Table 1. By default, the supply required
for the evaluation board comes from the SDP-H1 controller
board. The supply is regulated by the on-board ADP5070
switched mode power supply (SMPS), which generates the dual
supply, and the ADP7118 and the ADP7182 low dropout (LDO)
regulators reduce noise and generate the low noise, regulated,
positive and negative rails.

CONFIGURATION TAB
Reference Voltage Pop-Up Buttons
General Configuration
The reference voltage pop-up buttons (Label 5) set the reference
voltage used for calculating the results in the Waveform and
Histogram tabs. The evaluation board has an external 2.5 V
ADR441 reference; however, this reference can be bypassed
using this pop-up button, and the user can change the external
reference voltage value to ensure correct calculation of results in
the Waveform and Histogram tabs. Internal reference and
reference buffers can be selected using these pop-up buttons. If
AVDD3/AVSSx is selected as the reference, the REF (V) value
must be updated accordingly.
The general configuration controls (Label 2 in Figure 8) define
the voltage reference, external clock, the output data rate, number
of samples, and if the sigma delta (ΣΔ) is read continuously or

The SD errors pop-up buttons (Label 7) show the errors
detected on the SD channel.
The error test pop-up button (Label 11) enables and disables the
different error checkers implemented in the AD7770, AD7771,
and AD7779.
Gain, Offset, and Phase Pop-up Buttons
The gain, offset, and phase pop-up buttons (Label 8) allow the
user to calibrate the offset and gain of each specific SD channel.
After the phase compensation updates, click START to apply
the change.
START Button
Clicking START (Label 9) generates a pulse on the START pin
to reset the internal sinc filter, which ensures that any update on
the phase compensation register is correctly applied.
Control Configuration Pop-Up Button
The control configuration pop-up button (Label 10) allows the
user to configure features such as the power mode (must be set
to high power mode, unless a different clock is provided), the
common-mode voltage (VCM), the internal oscillator, and the
mode to update the ODR (SRC registers).
It is recommended not to change the SRC load source (Bit 7 in the
SRC_UPDATE register, Address 0x064), because SRC_LOAD_
SOURCE can only be enabled via the GUI. Setting Bit 7 of
Address 0x064 enables updating SRC via the hardware, which
is not supported on the current evaluation board.
Data Output Interface Pop-Up Button
The data output interface pop-up button (Label 12) adjusts the
DOUT header and driver strength.
SPI Interface Pop-Up Button
The SPI interface pop-up button (Label 13) adjusts the various
parameters for the SPI and shows any SPI errors.
SAR Input Pop-Up Button
The SAR input pop-up button (Label 14) allows the user to
select the input signal for the SAR ADC.
SAR Power Pop-Up Button
The SAR power pop-up button (Label 15) enables and disables
the SAR ADC. If the SAR is disabled, the SAR input mux is
disabled as well.
Status Bar
The status bar (Label 16) displays the status of the board and
indicates if the board is busy and cannot perform any other
action.
The SRC register can be updated manually; however, the update
is not reflected in the ODR (SPS) field.
Errors related to the memory map appear in this pop-up.

WAVEFORM TAB
Display Units and Axis Controls
Waveform Graph and Controls
Use the Display Units drop-down box (Label 22) to select
whether the data graph displays in units of voltages or codes.
This affects both the waveform graph and the histogram graph.
The axis controls can be switched between dynamic and fixed.
When dynamic is selected, the axis automatically adjusts to
show the entire range of the ADC results after each batch of
samples. When fixed is selected, the user can program the axis
ranges manually, and the ranges do not adjust automatically
after each sample batch.
The data waveform (Label 18) shows each successive sample of
the ADC output. The control tools (Label 20) in the graph allow
the user to zoom in on the data. Change the scales on the graph
by typing values into the x-axis and y-axis.
Analysis Channel
The noise/waveform analysis section (Label 24) and histogram
graph show the analysis of the channel selected via the Analysis
Ch drop-down box (Label 19).
Channel Selection
The channel selection control (Label 21) allows the user to
choose which channels display on the data waveform. It also
shows the analog inputs for that channel labeled next to the on
and off controls. These controls only affect the display of the
channels and do not have any effect on the channel settings in
the ADC register map.
If the value is selected as hex, the x-axis of the graph shows the
original data (twos complement). Due to the limitations of the
software, the number shows as signed 32 bits rather than signed
24 bits.
Save Data
Click Save (Label 23) to save the samples to an external file.
Waveform Analysis
The Waveform Analysis section (Label 24) displays the results
of the noise analysis for the selected analysis channel. The rms
noise is only applicable with a constant dc value.
