The conventional signal demodulator of a chopper amplifier can be substituted by track-and-hold (T/H) and averaging functions. This arrangement provides offset cancellation without requiring low-pass ...

Class D audio power amplifiers, also called PWM amplifiers, have been in use for many years. Systems such as wireline telephony, where high bandwidth was not critical were the initial application of ...

If you want to extract a signal from a huge amount of noise, a lock-in amplifier is the ideal tool. But when it comes to buying one, doing your homework first can avoid a costly mistake, advises ...

A high-side current-sense amplifier must be protected against reversed battery connections or inductive kickbacks or other negative-voltage transient. This Idea for Design describes a circuit using ...

Vishay has introduced a precision isolation amplifier with 5kVrms isolation test voltage and 150kV/μs typical (100kV/μs min) common-mode transient immunity: VIA0050DD. “Isolation amplifiers in the VIA ...
