LM9830 can correct for using its internal PGA.
Note 13:
PGA Gain Error is the maximum difference between the measured gain for any PGA code and the ideal gain calculated by using the formula
where

Note 14:
Interaction with an actual parallel port load (C
LOAD
> 200pF) can increase data settling time by as much as 100ns if the parallel port databus is precharged high.
For this reason, it is recommended that the parallel port be driven to 0x00h by the PC when not in the reverse transfer phase. When reading coefficient data from register 6
(register 3 = 00000XX1 binary), the EPP handshaking generated by the host PC may be faster than the data can settle. For this reason it is recommended that software
handshaking (“PS2” mode) be used when verifying coefficient data.
