A Class D amplifier provides better efficiency and thermal performance than a comparable Class AB amplifier, but implementing a Class D amplifier still requires attention to good electrical- and thermal-design practices. Most engineers use a ...

While measuring op-amp input capacitance, what should you focus on? The answer is that you must ensure the measurement accuracy isn’t degraded by the stray capacitance and inductance of the PCB or test setup. You can minimize these issues by ...

ADCs with differential inputs are becoming increasingly popular. This popularity isn't surprising, because differential inputs in the ADC offer several advantages: good common-mode noise rejection, a doubling of the available dynamic range ...

Certain designs need a programmable-gain amplifier with a wide gain range and high accuracy and common-mode rejection. Usually, it's wise to exploit a programmable-gain instrumentation amplifier, such as an AD625 . Unfortunately, the gain range ...

EDN The superbal circuit will be familiar to anyone involved in balanced signal transmission [1,2]; it is a differential amplifier which presents identical input impedances to both legs of a balanced line. Balanced loading is a necessity for the ...
