4317B–AVR–02/05

• Bit 5, 4– AMP1G1, 0: Amplifier 1 Gain Selection Bits

These 2 bits determine the gain of the amplifier 0.

The different setting are shown in Table 106.

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– AMP1TS1, AMP1TS0: Amplifier 1 Trigger Source Selection Bits

In accordance with the Table 107, these 2 bits select the event which will generate the

trigger for the amplifier 1. This trigger source is necessary to start the conversion on the

amplified channel.
