Single-ended-to-differential converter has resistor-programmable gain

摘要

Many applications-such as driving modern ADCs, transmitting signals over twisted-pair cables, and conditioning high-fidelity audio signals-require differential signaling to achieve higher signal-to-noise ratios, increased common-mode noise immunity, and lower second-harmonic distortion. This requirement presents a need for a circuit block that can convert single-ended signals to differential signals; that is, a single-ended-to-differential converter.
