OPA2810: Usage as a unity gain buffer and line driver

Part Number: OPA2810


I have a circuit with an AC large signal input +13V to minus 13V, 50Hz. My circuit has to operate from a single +5V supply.

I divide and shift the input signal with a 3 resistor (and a reference) circuit so that +13V translates to 5V and -13V translates to 0V.

From this point I need to perform the following:

1. Introduce the signal to 3 different window comparators

2. buffer this signal to an off-circuit data acquisition instrument (flexible input voltage, high impedance)

3. buffer this signal to be introduced into the ADC of a delfino.

I would highly appreciate advice on the following:

1. the following arrangement:

2. The choice of buffer for this task.

many thanks
