AD8627/AD8626/AD8625
APPLICATIONS
The AD862x is one of the smallest and most economical
JFETs offered. It has true single-supply capability and has
an input voltage range that extends below the negative rail,
allowing the part to accommodate input signals below ground.
The rail-to-rail output of the AD862x provides the maximum
dynamic range in many applications. To provide a low offset,
low noise, high impedance input stage, the AD862x uses
n-channel JFETs The input common-mode voltage extends
from 0.2 V below –V
S
to 2 V below +V
S
. Driving the input of the
amplifier, configured in unity gain buffer, closer than 2 V to the
positive rail causes an increase in common-mode voltage error,
as illustrated in Figure 15, and a loss of amplifier bandwidth.
This loss of bandwidth causes the rounding of the output
waveforms shown in Figure 39 and Figure 40, which have inputs
that are 1 V and 0 V from +V
S
, respectively.

The AD862x will not experience phase reversal with input
signals close to the positive rail, as shown in Figure 29. For input
voltages greater than +V
SY
, a resistor in series with the AD862x’s
noninverting input prevents phase reversal at the expense of
greater input voltage noise. This current limiting resistor should
also be used if there is a possibility of the input voltage
exceeding the positive supply by more than 300 mV, or if an
input voltage is applied to the AD862x when ±V
SY
= 0. Either of
these conditions will damage the amplifier if the condition
exists for more than 10 seconds. A 100 k resistor allows the
amplifier to withstand up to 10 V of continuous overvoltage,
while increasing the input voltage noise by a negligible amount.
