GENERAL DESCRIPTION
The AD706 is a dual, low power, bipolar op amp that has the
low input bias current of a JFET amplifier, but which offers a
significantly lower I
bipolar input transistors to achieve picoampere input bias current
levels (similar to FET input amplifiers at room temperature),
while its I
JFET amp, for which I
increase at 125°C). The AD706 also achieves the microvolt
offset voltage and low noise characteristics of a precision bipolar
input amplifier.
Since it has < 200 pA of bias current, the AD706 does not
require the commonly used “balancing” resistor. Furthermore,
the current noise is only 50 fA/√Hz, which makes this amplifier
usable with very high source impedances. At 600 A max supply
current (per amplifier), the AD706 is well suited for today’s
high density boards.
The AD706 is an excellent choice for use in low frequency
active filters in 12-bit and 14-bit data acquisition systems, in
precision instrumentation, and as a high quality integrator. The
AD706 is internally compensated for unity gain and is available
in five performance grades. The AD706J is rated over the
commercial temperature range of 0°C to +70°C. The AD706A is
rated for the extended industrial temperature range of –40°C
to +85°C.
The AD706 is offered in two varieties of an 8-lead package:
plastic mini-DIP and surface-mount (SOIC).
