another question -----high speed adc

[Joseph_lee]

Hi all,
I would like to hear some opinions about high speed 8 bit adc (betw. 200 and 1000 Msps). I intend to use it in a DSO, and I still don't know yet which one is the best (performance, price, easy integration....). Thanks a lot.

Added after 3 minutes:

thanks for your enthusiasm heart!!!

Hi
check the AD parts.

For high speed applications, folding or pipeline are good choices.

 

[Alvinnju]

pipeline is a good choice.

 

[daredge]

pipeline probably can probably go up to 200M (for 8 bit); flash is the only way for speed > 200Mhz.

I think pipelining only increase throughput but introduce some latency may not be best in high speed application..

u can go into the websites of AD or TI . there are some introduction of production of high speed ADC.

Fairchild: SPT7721, SPT7722 - 8-bit, 250 MSPS ADC
Intersil: HI3286 - 8-Bit, 160MSPS, Flash ADC
Linear: LTC2230, LTC2231 - 10-Bit,170Msps_135Msps ADCs
Maxim: MAX106 - 5V, 600Msps, 8-Bit ADC with On-Chip 2.2GHz Bandwidth Track_Hold Amplifier; MAX1121 - 1.8V, 8-Bit, 250Msps
National: ADC081000 - High Performance, Low Power 8-Bit, 1 GSPS ADC; ADC08200 - 8-Bit, 20 MSPS to 200 MSPS, 1.05 mW_MSPS ADC

u can link the websites of AD , TI or LT. i think their documents will be useful for u.

what do u mean by DSO.please clarify ur questions further.
