4378C–AVR–09/08
These 2 bits determine the gain of the amplifier 0.
The different setting are shown in
Table 19-3.
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 1, 0– AMP0TS1, AMP0TS0: Amplifier 0 Trigger Source Selection Bits
In accordance with the Table 19-4, 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.
