dsp with adc
I have a design to do ,And i need to bring the cost as low as possible
I need to control a servo motor in a very particular form .
The servo has a capacitance positioning system .So i need to to sample this signal at least with 1 to 2 MSP .. I process this signal an then the DACs are used to control de DRIVER for the motor . I have been imposed the motor and the Positioning system .I'm redesigning the controller replacing all the all analog electronics : MICRO and at least 8 Analog OPs and a lot of resistors caps and the old DAC ..
basically i want to use just one chip to do it all . But i'm having hard time finding a DSP with DACs .. 12 bits ADC are plenty but the DACs are not commun . The only chip i'm considering is the new Analog device's ARM7
mixed signal .But the product is too new and the silicon is buggy .
Any suggestions?
(the chip has to be < $15 and also with 32k to 64k flash and ram)
