channel array to pas through amplifier

channel array to gain

Hi all !

I have 128 channels, each channel output's a signals in the range of 10mV to 0.1V
and from 0Hz to 1kHz, and I have to increase all of them by X100.

My question is refer to all of you experienced folks:

is there a device that acts as array of amps for this specifications?
and if not,What is the best method to save supplies power? I'm honestly don't belive that I have to use 128 amps...

Sorry for the rookie's question...

thanks,
Johana

1kHz is 1ms period. If you need to digitize the signals, you could use an analog multiplexer to connect to an amplifier which drives the ADC. Each channel would get about 4us settling time after each transition.
