Figure 8. MMB3 Block Diagram
The MMB3 was designed to be used as a stand-alone demonstration platform for low-speed data
converters. It features an onboard, 20-bit digital-to-analog converter (DAC) that can be used as a signal
source for an ADC under test, and has a joystick for control of functions on the board when it is not
controlled by a PC. These features are experimental and not supported in the ADS1248EVM-PDK at
this time.
The MMB3 derives power from the USB interface, and generates +5VD, 3.3V, and 1.8V, as well as +5VA
and
–5VA and ±10V. The ±10V is supplied to the daughtercard power connector as +VA and –VA.
The MMB3 is not sold as a microcontroller development board, and it is not available separately. TI cannot
offer support for the MMB3 except as part of an EVM kit. For schematics or other information about the
MMB3, contact Texas Instruments.

EVM Power Supply
The ADS1248EVM-PDK is powered completely from the USB connection on the MMB3. The MMB3
provides 3.3V and
±5V to the ADS1248EVM.

Running the Software and Download of Firmware to MMB3
NOTE:
The software is continually under development. These instructions and screen images are
current at the time of this writing, but may not exactly match future releases.
The program for evaluating the ADS1248EVM-PDK is called ADCPro. This program uses plug-ins to
communicate with the EVM. The ADS1248EVM-PDK plug-in is included in the ADS1248EVM-PDK
package.
