Difference amplifier uses digital potentiometers - 30-May-02 Issue of EDN You
sometimes need to measure a small signal in the presence of a large common-mode
signal. Traditional instrumentation amplifiers that use two or three op amps in
their internal structure find common use in these applications. The circuit in
Figure 1 presents an alternative approach that is useful when low cost and low drift
are important, but when you don't need high precision.... [Design Idea by Reza

Differential Amp Drives High-Speed ADC - 06/21/01 EDN-Design Ideas The
schematic in Figure 1 is the discrete-element version of an A/D-converter drive
circuit. The circuit converts a single-ended input to a differential output. The
ADC's reference voltage determines the common-mode range of the differential
outputs. The circuit contains two AD9631 amplifiers—one connected in noninverting
mode, and the other connected in....PDF has several circuits, scroll to find this

Differential amp needs no power source - 2-May-02 Issue of EDN A
true-differential, power-source-free, high-input-impedance amplifier with bipolar
output would present distinct advantages in remote devices. Such an amplifier, with
its bipolar output, would be a better choice than a unipolar, 4- to 20-mA device. It
would also improve on common-mode performance. In Figure 1, a Maxim MAX319 analog
switch, IC2, feeds the power from the coaxial signal cable to.... [Design Idea by By
