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.

thanks for your enthusiasm heart!!!
 

Hi
check the AD parts.

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

pipeline is a good choice.
 

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.
 

I know following parts:
AD: AD9480, AD9481 - 250 MSPS 3.3V ADC
Atmel: AT84AD001B - Dual 8-bit 1 Gsps ADC, 3.3VDC, 1.4W; TS83102G0B - 10-bit 2 Gsps ADC, 5VDC, 4.6W; TS8308500 - ADC 8-bit, 500 Msps, 5VDC, 3.8W,
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.
