Data Sheet AD8628/AD8629/AD8630 FUNCTIONAL DESCRIPTION The AD8628/AD8629/AD8630 are single-supply, ultrahigh 1/f NOISE precision rail-to-rail input and output operational amplifiers. 1/f noise, also known as pink noise, is a major contributor to The typical offset voltage of less than 1 µV allows these amplifiers errors in dc-coupled measurements. This 1/f noise error term to be easily configured for high gains without risk of excessive can be in the range of several µV or more, and, when amplified output voltage errors. The extremely small temperature drift with the closed-loop gain of the circuit, can show up as a large of 2 nV/°C ensures a minimum offset voltage error over their output offset. For example, when an amplifier with a 5 µV p-p entire temperature range of −40°C to +125°C, making these 1/f noise is configured for a gain of 1000, its output has 5 mV of amplifiers ideal for a variety of sensitive measurement applica- error due to the 1/f noise. However, the AD8628/AD8629/AD8630 tions in harsh operating environments. eliminate 1/f noise internally, thereby greatly reducing output errors. The AD8628/AD8629/AD8630 achieve a high degree of precision The internal elimination of 1/f noise is accomplished as follows. through a patented combination of auto-zeroing and chopping. 1/f noise appears as a slowly varying offset to the AD8628/AD8629/ This unique topology allows the AD8628/AD8629/AD8630 to AD8630 inputs. Auto-zeroing corrects any dc or low frequency maintain their low offset voltage over a wide temperature range offset. Therefore, the 1/f noise component is essentially removed, and over their operating lifetime. The AD8628/AD8629/AD8630 leaving the AD8628/AD8629/AD8630 free of 1/f noise. also optimize the noise and bandwidth over previous generations One advantage that the AD8628/AD8629/AD8630 bring to of auto-zero amplifiers, offering the lowest voltage noise of any system applications over competitive auto-zero amplifiers is their auto-zero amplifier by more than 50%. very low noise. The comparison shown in Figure 49 indicates Previous designs used either auto-zeroing or chopping to add an input-referred noise density of 19.4 nV/√Hz at 1 kHz for precision to the specifications of an amplifier. Auto-zeroing the AD8628, which is much better than the Competitor A results in low noise energy at the auto-zeroing frequency, at the and Competitor B. The noise is flat from dc to 1.5 kHz, slowly expense of higher low frequency noise due to aliasing of wideband increasing up to 20 kHz. The lower noise at low frequency is noise into the auto-zeroed frequency band. Chopping results in desirable where auto-zero amplifiers are widely used. lower low frequency noise at the expense of larger noise energy 120 at the chopping frequency.

This ensures that the output does not reverse its phase. CH1 = 50mV/DIV OVERLOAD RECOVERY TIME CH2 = 1V/DIV VIN AV = –50 Many auto-zero amplifiers are plagued by a long overload recovery time, often in ms, due to the complicated settling behavior of the internal nulling loops after saturation of the outputs.
