AMC1400: Isolated current output <= 20mA

Part Number: AMC1400
Other Parts Discussed in Thread: AMC3302, AMC3301, AMC3311, AMC3330

Tool/software:

Hello,
For my application (transcutaneous electrical stimulation) I need an analog sine wave output of 0-20mA. This must be an isolated, amplified version of an analog sine wave input signal that I can choose to be voltage or current. Ideally, the isolated output power would be integrated or not needed (as in the case of a transformer).
One way to accomplish this may be to have a current input into a current transformer with a 1:1 ratio. However, most current transformers seem designed to sense high currents and they step down the current quite a bit.
Another possibility would be some sort of analog isolation amplifier with integrated power, but I can only find digital isolation amplifiers with integrated power.
Does TI make any possible solutions for this?
Thank you for your time.
