While I don't know about the SSM2013, the Signetics NE572 looks
interesting.  Signetics claims that a dynamic range of greater than
110 dB is possible.  Residual noise is typically 6 uV for the
device.  The chip contains a gain cell, log amp, and output buffer.
See page 15-17 of the 1982 (what can I say, I'm an Old Fart) edtion
of the Signetics Analog Data Manual.
