is it possible to sample 4khz frequency

Other Parts Discussed in Thread: MSP430G2252

Hello

Is it possible to sample 4khz frequency  in adc using controller msp430g2252.If it is possible means pls suggest  some answers 

  • If you check out device datasheet you will find that the integrated converter samples data with speed of 200-ksps. Therefore you should be able to capture 4kHz signal without a problem.

  • Short answer: yes.

    Long answer: sampling rate depends on ADC clock frequency (default: 6MHz), clock divider (1..10), sampling time (4,8,16 or 64 clock cycles) and conversion time (13 clock cycles). Precise frequencies can be achieved by starting each conversion individually, by hardware (a timer trigger) or software. 4kHz are no problem with any method.
