OPA347: DC Output Smoothing decay rate too long

Part Number: OPA347
Other Parts Discussed in Thread: TINA-TI, INA827, , TS5A9411

I have a design which will smooth a differential input signal from an In Amp, provide some gain with a potentiometer and output the signal. This is all fine but when the signal is removed, the output takes too long to settle due to the integrator capacitor. The decay rate is far too long. Is there a better way of doing this?

I have tried a precision peak detector but this adds time for the signal to ramp up.

This is a single supply design. The input frequency is from 10Hz to 1KHz.

I want an output signal like the one below but when I remove the input signal, I want the output to be 0V within 200ms.

I could do with simulating the sinewave for a small finite amount of time and then seeing the decay rate when the signal disappears, is there a way to do this in Tina-TI?

The design is attached, I hope someone can help.DC Smoothing circuit.TSC
