To design a low noise amplifier with gain of 100 ,passing band of 0.01 Hz to 200 Hz, I/p signal source impedance : 100 kohm + 20pF ,o/p load of 5pF, dynamic and static error within 1% and NF < 5 dB. and consider 1/f noise
Thank you for your interest in ADI products. I believe ADA4528-1 could be a good candidate for your application. ADA4528-1 is a single, precision, ultralow noise, rail-to-rail input/output, zero-drift operational amplifier. It has at typical offset voltage of 0.3uV with a drift of 0.002uV/degC, a CMRR of not less than 137dB and PSRR of at least 130dB. ADA4528-1 is designed to have no 1/f noise. It's 0.1Hz to 10Hz voltage noise is only 99nVp-p. AN-1114 further discusses the features of ADA4528-1. ADA4528-1 is well suited for applications in which error sources cannot be tolerated.
I hope this helps.
