AD8628/AD8629/AD8630 FUNCTIONAL DESCRIPTION The AD8628/AD8629/AD8630 are single-supply, ultrahigh precision rail-to-rail input and output operational amplifiers. The typical offset voltage of less than 1 μV allows these amplifiers to be easily configured for high gains without risk of excessive output voltage ...
Page 15
PEAK-TO-PEAK NOISE Because of the ping-pong action between auto-zeroing and chopping, the peak-to-peak noise of the AD8628/AD8629/ AD8630 is much lower than the competition. Figure 50 and Figure 51 show this comparison. e p-p = 0.5µ 0.1Hz ...

AD8628/AD8629/AD8630 INPUT OVERVOLTAGE PROTECTION Although the AD8628/AD8629/AD8630 are rail-to-rail input amplifiers, care should be taken to ensure that the potential difference between the inputs does not exceed the supply voltage. Under normal negative feedback operating conditions, the amplifier corrects its ...
