INPUT CHARACTERISTICS
The ADA4622-1/ADA4622-2/ADA4622-4 input stage consists of
N-channel JFETs that provide low offset, low noise, and high impe-
dance. The minimum input common-mode voltage extends from
−0.2 mV below V− to 1 V less than V+. Driving the input closer to
the positive rail causes loss of amplifier bandwidth and increased
common-mode voltage error. Figure 81 shows the rounding of the
output due to the loss of bandwidth. The input and output are
superimposed.
Figure 81. Bandwidth Limiting due to Headroom Requirements
The ADA4622-1/ADA4622-2/ADA4622-4 do not exhibit phase re-
versal for input voltages up to V+. For input voltages greater than
V+, a 10 kΩ resistor in series with the noninverting input prevents
phase reversal at the expense of higher noise (see Figure 82).
Figure 82. No Phase Reversal
Because the input stage uses N-channel JFETs, the input current
during normal operation is negative. However, the input bias current
changes direction as the input voltage approaches V+ due to
internal junctions becoming forward-biased (see Figure 83).
