THEORY OF OPERATION
The AD626 is a differential amplier consisting of a precision
balanced attenuator, a very low drift preamplier (A1), and an
output buffer amplier (A2). It has been designed so that small
differential signals can be accurately amplied and ltered in the
presence of large common-mode voltages (VCM), without the use
of any other active components.
Figure 4 shows the main elements of the AD626. The signal inputs
at Pins 1 and 8 are rst applied to dual resistive attenuators R1
through R4 whose purpose is to reduce the peak common-mode
voltage at the input to the preamplier—a feedback stage based
on the very low drift op amp A1. This allows the differential
input voltage to be accurately amplied in the presence of large
common-mode voltages six times greater than that which can be
tolerated by the actual input to A1. As a result, the input CMR
extends to six times the quantity (VS – 1 V). The overall common-
mode error is minimized by precise laser-trimming of R3 and R4,
thus giving the AD626 a common-mode rejection ratio (CMRR)
of at least 10,000:1 (80 dB).
To minimize the effect of spurious RF signals at the inputs due to
rectication at the input to A1, small lter capacitors C1 and C2
are included.
The output of A1 is connected to the input of A2 via a 100 k
(R12) resistor to facilitate the low-pass ltering of the signal of
interest (see Low-Pass Filtering section).
The 200 k
input impedance of the AD626 requires that the source
resistance driving this amplier be low in value (<1 k )—this is
