Single ended to differential conversion can be achieved using a RRO amplifier on a single supply with little headroom impact. This is at the expense of a resistive input. In this configuration R1=R2, ...

The design topology Figure 1 depicts a current feedback amplifier (CFA) having a pseudo-differential topology having two identical single-ended current feedback amplifiers (SCFA) connected in a ...

The analogue path provides a lesson for anyone interested in instrumentation signal path design, with the signal conditioning and compensation circuits feeding an AD8130 differential amplifier.
