Hi, i have a project to make a interface ciruitry of mems gyroscope. I will use discrete componen. I want to ask you, can i use the amplifier with specification below low for frequency ? about 50 hz - 140 hz.

Features
- 370 MHz −3 dB bandwidth (VOUT= 0.5 VPP)
- 50 MHz 0.1 dB bandwidth
- 2400 V/µs slew Rate
- 18 ns settling time to 0.05%
- −94/−96 dB HD2/HD3 @ 5 MHz

thank you
 
Why would you use such a high frequency opamp to amplify 50 to 140Hz? Seems like you need super low noise, not high frequencies?
 
As Mike suggested, you should use a low noise, moderate frequency amp, such as an OP-27 for example.
 
i need differential output op amp.. i cant find the op amp for low frequency..
hi,
What you are looking for is a 'fully differential/difference amplifier'
**broken link removed**

Look thru these two pdf's, I find them helpful.
