The Impedance Scaling Network (AISN) gain can be varied from −0.9375 • GIN to +0.9375 • GIN in
multiples of 0.0625 • GIN.
The gain coefficient is decoded using the following equation:

a value of AISN = 0000* indicates a gain of 0 (cutoff).

the pins set to the Input mode is latched, but does not appear at the pins. The CD1B bit is only valid if the
E1 Multiplex mode is enabled (EE1 = 1). C7 and C6 are outputs only and are not available on all package
types.
