Voltage Reference
The ADS7953EVM has three sources for the reference voltage. Jumper W2 can select the REFP voltage
from either the REF5025(U3) or from an external source applied to P1.18. Jumper W3 can select the
REFM voltage from either the analog ground (AGND) or from an external source applied to P1.20.
6
EVM Operation
The following section provides information on the analog input, digital control, and general operating
conditions of the ADS7953EVM.
6.1
Analog Input
Eight of the analog input sources (channels 0-7) can be applied directly to P1 (top or bottom side) or
through signal-conditioning modules available for the modular EVM system. The additional eight channel
sources (CH8-CH15) can be applied to connector J1. The analog input range on the EVM is identical to
that of the installed device and is dependent on the RANGE setting of the ADC (0 to 5V or 0 to 2.5V)
Each input signal can be configured to connect directly to the analog inputs of the ADS7953 through a
33Ω series resistor with an 0.027pF capacitor to AGND. The input to CH0 can use the OPA365 buffer that
is provided (default condition, W4 jumpered pins 1-2). Jumper W4 can be placed on pins 2-3 to bypass
the unity gain buffer configuration of the OPA365.
6.2
Digital Control
The digital control signals can be applied directly to P5 (top or bottom side). The modular ADS7953EVM
can also be connected directly to a DSP or microcontroller interface board, such as the 5-6KInterface or
HPA-MCUInterface boards available from Texas Instruments. When purchased as part of a PDK, the
ADS7953EVM can be controlled by the MMB0. For a list of compatible interface and/or accessory boards
for the EVM or the ADS7953, see the relevant product folder on the TI website. All of the digital signals
are controlled directly with pins on P2.

ADS7953EVM-PDK Power Supply
The analog portion of the ADS7953EVM can either be powered by a 5V source generated via an external
power supply using the included CA-2186 cable or by applying the +5VA to the connector on the MMB0
board. The MMB0 board will provide the digital 5V and 3.3V to the ADS7953EVM. To provide +5VA to the
ADS7953EVM from the MMB0 board, make sure the jumper at J13 (on the MMB0) is closed from +5V to
+5VA.

Evaluating Performance with the ADCPro Software
The evaluation software is based on ADCPro, a program that operates using a variety of plug-ins. (The
ADS7953EVM plug-in is installed as described in the previous section.)
To use ADCPro, load an EVM plug-in and a test plug-in. To load an EVM plug-in, select it from the EVM
menu. To load a test plug-in, select it from the Test menu. To unload a plug-in, select the Unload option
from the corresponding menu.
Only one of each kind of plug-in can be loaded at a time. If selecting a different plugin, the previous plugin
is unloaded.
8.1
Using the ADS7953EVM-PDK Plug-in
The ADS7953EVM-PDK plug-in for ADCPro provides complete control over all settings of the ADS7953. It
consists of a tabbed interface (see Figure 19), with different functions available on different tabs. These
controls are described in this section.
The user can adjust the ADS7953EVM settings when not acquiring data. During acquisition, all controls
are disabled and settings may not be changed.
When a setting is changed on the ADS7953EVM plug-in, the setting immediately updates on the board.
Settings on the ADS7953EVM correspond to settings described in the ADS7953 product data sheet; see
the ADS7953 data sheet for details.
Because the effective sampling rate of the ADS7953 depends upon settings of the Clock Freq and the
number of channels being sampled, the Sampling Rate indicator in the upper right corner of the plug-in
interface is always visible and updates whenever a setting changes that affects the effective 'per-channel'
sampling rate.

Channel Tab
The ADS7953 can acquire from one to sixteen channels sequentially or in a user defined pattern. The
Channel Tab (as shown in Figure 19) provides the control to turn each channel on or off. By default,
manual channel mode is enabled. In manual mode, any single channel may be selected for conversion.

In addition, the Manual Control button (shown in Figure 20) can be used to enable or disable auto scan
modes 1 and 2. Auto 1 Mode allows the selection of any number of channels from the channel selection
list. Auto 2 Mode allows the selection of the highest channel to convert. All channels below this will be
converted once this selection is made by pressing the 'Accept Selection' button.

Other Tab
The ADS7953 requires a clock to operate. The maximum frequency is selected by default for the different
operating modes, providing the maximum 1MSPS throughput rate specified in the datasheet.
The clock setting can be modified in this tab by accepting the default SPI or clock stop mode, a
continuous clock mode with the fastest possible serial clock, or a continuous clock mode with a variable
frequency.
The analog input range can also be specified in this tab as well as the contents of the four MSBs of
channel data (GPIO status or Channel Address of the conversion results).

Alarm Tab
The ADS7953 offers configurable alarm outputs for both high and low alarm selections. The configuration
of the alarm function takes place in two steps, the first of which is the setting of the alarm limits. In the
Alarm Tab, the hex values for high and low limits are entered for each channel requiring the alarm
function. To enable the alarm functions, the GPIO Function tab must be considered next.

GPIO Function Tab
The GPIO0, GPIO1, GPIO2 and GPIO3 pins on the ADS7953 can function as simple general purpose
inputs/outputs or as specialized control and monitor functions. The alarm function described in the
previous section is processed by GPIO0 and GPIO1. Refer to the data sheet for specific details on GPIO0
and GPIO1 options. GPIO2 can be used to configure the input range of the ADS7953 (2.5V max or 5.0V
max), and GPIO3 can be used as a power down input pin.

The GPIO Tab provides a means to monitor and control GPIO functions. If a GPIO is selected in the GPIO
Function tab to perform a specialized function, it will appear 'grayed out' in the GPIO tab. For pins
configured as GP outputs, a push button will enable the user to set the desired output state. GP Inputs are
monitored with an LED display (bright green = logic high).
