Other Parts Discussed in Thread: TMS320C6745

HI,

      Here am using a kit TMS320C6745 with xds100 usb emulator.

specficetion of kit:

processor : TMS320C6745

 adc : MCP3202 (12 BIT SPI ADC)

dac : no

sdram : 64k

in my kit there is no dac ic at all ., so i cant able see the waveforms type of output. Now i planned to design my KIT with DAC. so., please suggest SOME ADC & DAC for the best suit for TMS320C6745.

    The AIC3106 that I mentioned on your other thread is a good choice, but it may have more capability than what you want. The biggest advantage is that the EVM has driver software that you can easily re-use with this device.

    It seems odd to be using an MCU as just an ADC. But if that is what you want to do, you can probably find several TI MCUs that will have both ADC and DAC.

    Or you may find some TI DSPs with both. There are C2000 devices that have built-in ADCs and then we use the PWMs into an Resistor-Capacitor filter to act as a DAC. Even though the C2000's are called MCUs, they speak DSP pretty well.

    Or you can simply replace the MCP part with an MSP430 that has both ADC and DAC plus I2C and very low power consumption.

    Do you really only have 64k of SDRAM?

    What you really need to do is to go to TI.com and select some of the Product types that you are interested in, like Data Converters or DSP or MCUs. Each of those links will lead you to a page with a Selection Tool. You can use those Selection Tools to find exactly what you want. There are a very large number of devices, but the Selection Tools let you quickly narrow down the search to those parts that meet your requirements for speed and capability.
