The TSZ121 is a chopper amplifier with an input offset voltage max of 5µV @25°C. Due to the switching mode, some injection charge appears on the input pins of a chopper amplifier, this switching ...

Chopper op amps offer very low offset voltage and dramatically reduce low frequency 1/f (flicker) noise. How do they do it? Here’s a quick-read on the tricks. The input stage of a chopper op amp is ...

Chopper-stabilized op amps constantly correct low-frequency errors across the inputs of the amplifier, making them attractive alternatives to conventional op amps in many industrial, medical ...
