Figure 46. 0.1 dB Gain Flatness for the Circuit of Figure 44
AC-COUPLED LINE RECEIVER
The AD830 is configurable as an ac-coupled differential
amplifier on a single- or bipolar-supply voltage. All that is
needed is inclusion of a few noncritical passive components, as
illustrated in Figure 47. A simple resistive network at the X GM
input establishes a common-mode bias. Here, the common
mode is centered at 6 V, but in principle can be any voltage
within the common-mode limits of the AD830. The 10 kΩ
resistors to each input bias the X GM stage with sufficiently high
impedance to keep the input coupling corner frequency low, but
not too large so that residual bias current induced offset voltage
becomes troublesome. For dual-supply operation, the 10 kΩ
resistors may go directly to ground. The output common is
conveniently set by a Zener diode for a low impedance
reference to preserve the high frequency CMR. However, a
simple resistive divider works fine, and good high frequency
CMR can be maintained by placing a compensating resistor in
series with the +Y input. The excellent CMRR response of the
circuit is shown in Figure 48. A plot of the 0.1 dB flatness from
10 Hz is also shown. With the use of 10 μF capacitors, the CMR
is >90 dB down to a few tens of hertz. This level of performance
is almost impossible to achieve with discrete solutions.
