Table 21-12. Amplifier 2 Gain Selection
To ensure an accurate result, after the gain value has been changed, the amplifier input needs
to have a quite stable input value during at least 4 Amplifier synchronization clock periods.
• Bit 3 – AMPCMP2: Amplifier 2 - Comparator 2 connection
Set this bit to connect the amplifier 2 to the comparator 2 positive input. In this configuration the
comparator clock is adapted to the amplifier clock and AMP2TS2,AMP2TS1, AMP2TS0 bits
have no effect.
Clear this bit to normally use the Amplifier 2.
• Bit 2:0 – AMP2TS[2:0]: Amplifier 2 Clock Source Selection Bits
In accordance with the
for the amplifier 1. This clock source is necessary to start the conversion on the amplified
channel.
