Programmable logic controllers (PLCs) and programmable automation controllers (PACs) are industrial computers constructed and adapted for manufacturing environments. These computers are the brains of a manufacturing operation, providing highly reliable control of automation equipment. PLCs and PACs are very similar to each other...
Using a Differential I/O Amplifier in Single-Ended Applications
09.04.2017 · Articles
Recent advances in low voltage silicon germanium and BiCMOS processes have allowed the design and production of very high speed amplifiers. Because the processes are low voltage, most of the amplifier designs have incorporated differential inputs and outputs to regain and maximize total output signal swing. Since many low-voltage applications are single-ended, the questions arise, “How can I use a differential I/O amplifier in a single-ended application?”...
