4.3 Programmable Gain Amplifier (PGA) Performance Specifications
It should be noted that the PGA and LPF in the receive path must be AC coupled to avoid problems with ampli-
fying any offsets.
Both the PGA and the amplifiers are specified in terms of the silicon only. This is to allow the system design to
be more flexible. The appendices show how to convert some of the silicon specs to system specs.
Table 5. PGA performance Specifications
8/26
Unless otherwise specified, NOM specifications apply for VCC=5.0V, temperature range outlined in Table 4.4,
nominal process and bias current. MAX and MIN performances with 5% variation on VCC, -40 <= T
and worst case process and bias current and a minimum load of 440 W.

D=11
<1>This is a nominal specification. 6 dB of margin should be added to arrive at a worst case spec.
