A simple architecture for a configurable op-amp or differential difference amplifier (DDA) is presented. The circuitry can be configured as an input/output rail to rail high-speed op-amp, or as a DDA.

This paper describes a 1-V wide-input range and high linearity transconductance input stage that uses poly resistor and input-impedance boosting technique. Using the proposed transconductor, an op amp ...

The new MXW70 power stereo amplifier has the same compact dimensions as the MXN10 streamer, meaning they can be stacked together to create a rather sleek hi-fi system that's ideal for smaller spaces.
