PGA281: Front circuitry for PG281

Part Number:PGA281

Hello,

I am using PGA281 for sensors data amplification.

There are various types of sensors.

Pressure sensors(Vout max 20 mVpp),Load cell(Vout max 20 mVpp),DC accelerometer(Vout max 2 Vpp) & Vibration sensors(Vout max 5 V).

Sensors Bw will be 5 KHz max.

Sensors output impedance will be less than 300 ohm.

I am using ADS8688A for data acquisitions from these sensors.

I need appropriate isolator at input side of signal conditioning befor PGA281. Please suggest??

For covering full dynamic range of ADC, i need higher gain so i am integrating this PGA281 with AD8421.
