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 ...

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 ...
