• Bit 5, 4– AMP0G1, 0: Amplifier 0 Gain Selection Bits
These 2 bits determine the gain of the amplifier 0.
The different setting are shown in
Table 17-7.
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– AMP0GS: Amplifier 0 Ground Select of AMP0
This bit select negative input of the amplifier:
Set this bit to ground the Amplifier 0 negative input.
Clear this bit to normally use the Amplifier 0 differential input.
• Bit 1, 0– AMP0TS1, AMP0TS0: Amplifier 0 Trigger Source Selection Bits
In accordance with the Table 17-8, these 2 bits select the event which will generate the trigger for the
amplifier 0. This trigger source is necessary to start the conversion on the amplified channel.
