Appendix: Setting Up the ADS7924EVM-PDK

Figure 23. MMB3

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 user control of functions on the board when it is not

controlled by a PC. These features are experimental and not supported in the ADS7924EVM-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 ±10V. The ±10V is supplied to the daughtercard power connector as +VA and –VA.

The MMB3 is not sold as a DSP 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.
